XFrames is an XML application for composing documents together, replacing HTML Frames. By being a separate application from XHTML, it allows content negotiation to determine if the user agent accepts frames; by encoding the 'population' of frames in the URI, it allows framesets to be bookmarked.

This section is informative.
Frames were introduced into HTML at version 4.0 [HTML4]. They introduced a manner of composing several HTML documents into a single view to create an application-like interface.
However, Frames introduced several usability problem that caused several commentators to advise Web site builders to avoid them at all costs. Examples of such usability problems are:
noframes markup is
necessary for user agents that don't support frames. However, almost no
one produces noframes content, and so it ruins Web searches,
since search engines are examples of user agents that do not support
frames.This document defines a separate XML application, not a part of XHTML per se, that allows similar functionality to HTML Frames, with fewer usability problems, principally by making the content of the frameset visible in its URI.
This section is normative.
This specification defines an XML application called XFrames. It uses the
XML Namespaces [NAME] identifier:
http://www.w3.org/2002/06/xframes/
All examples in this document are informative.
The remainder of this section describes the elements and attributes in XFrames, and their semantics.
The XFrames Module supports the following element and attributes:
| Element | Attributes | Content Model |
|---|---|---|
| frames | class (NMTOKENS), xml:id (ID), title (CDATA), xml:base (URI) | head?, (group | frame+) |
| head | class (NMTOKENS), xml:id (ID), title (CDATA) | title, style* |
| title | class (NMTOKENS), xml:id (ID), title (CDATA) | PCDATA |
| style | class (NMTOKENS), xml:id (ID), title (CDATA), type* (ContentType), media (MediaDesc), source (URI) | PCDATA |
| group | class (NMTOKENS), xml:id (ID), title (CDATA), compose ("vertical"* | "horizontal" | "single" | "free" | QName), xml:base (URI) | (group | frame)+ |
| frame | EMPTY |
Implementations: DTD, RELAX NG, XML Schema
Note that the datatype called 'URI' in this specification refers to the Internationalized Resource Identifier (IRI) [IRI].
Example XFrames document:
<frames xmlns="http://www.w3.org/2002/06/xframes/">
<head>
<title>Home page</title>
<style type="text/css">
#banner {height: 10em }
#atoz, #nav {width: 20%}
#footer {height: 4em }
</style>
</head>
<group compose="vertical">
<frame xml:id="banner" source="banner.xhtml"/>
<group compose="horizontal">
<frame xml:id="atoz" source="atoz.xhtml"/>
<frame xml:id="main" source="news.xhtml"/>
<frame xml:id="nav" source="nav.xhtml"/>
</group>
<frame xml:id="footer" source="copyright.xhtml"/>
</group>
</frames>An XFrames document is a specification for composing several documents,
potentially of different types, together in a view. The frames
element forms the container for the composed document. The individual
sub-documents ('frames') may be composed together in a rectangular space by
placing them next to, or above, each other in rows and columns, or they may
be displayed as separate movable window-like panes, or as tabbed panes, or in
any other suitable manner. The collection of frames in an XFrames document is
referred to as a frameset. The frames element has the
following additional attribute on top of the set of attributes common to all
elements:
xml:baseThe head element contains meta-data about the document,
specifying a title, and a style sheet.
The title element contains an identifying text for the
document, that may be used by a user agent to label the document.
The style element allows the specification of styling
instructions that affect the presentation of the frames in the document.
Apart from common attributes, the style element has the
following attributes:
typesourcestyle element; otherwise the content of the
style element is used.mediaThe group element specifies a series of groups and single
frames. The groups and single frames are positioned together according to
styling applied to them; in the absence of styling, the compose
attribute should be used by the user agent as an indication of how the frames
are to be composed. There is one additional attribute:
xml:baseThe frame element is a place holder for the content of a
document. It has one additional attribute:
sourceThe compose attribute supplies a suggestion to the user agent
for how a group of frames should be composed. Styling applied from a
stylesheet may override or ignore the suggestion; user agents for particular
devices may find it necessary to use other styling: for instance a device
with a very small screen may only offer a presentation of the frames' titles,
and allow each frame to be selected individually (a variant of 'single');
otherwise a user agent should use the suggestion for positioning.
The compose attribute has the following values:
verticalThe grouped elements are tiled vertically above each other. (A
group with compose="vertical" is referred to further in
this specification as a column.)
horizontalThe grouped elements are tiled horizontally next to each other. (A
group with compose="horizontal" is referred to further in
this specification as a row.)
singleAt any moment only one of the grouped frames is visible; any of the others can be made visible by selecting it. The user must be able to see that there are other frames available, and the user must be able to access any one of them. The method used to select another frame is not defined. It may be done using a series of tabs, a menu, or some other means. The frame or group's title should be used as the identifier used for selection.
freeThe elements are made available as free-standing moveable overlappable windows within the space available.
A QNameThis specification makes no normative statement about how these values affect layout. It is there to allow implementations to supply other layout possibilities. In the absence of any other styling information, when an implementation encounters a value it does not recognize, it should treat it as equivalent to vertical.
xml:idThis attribute assigns a name to an element. This name must be unique in an XFrames document. It may be used as a style sheet selector, a target anchor for hypertext links or as a means to reference a particular element for general purpose processing by user agents.
classThis attribute assigns a class name or set of class names to an element. Any number of elements may be assigned the same class name or names. Multiple class names must be separated by white space characters. It may be used as a style sheet selector (when an author wishes to assign style information to a set of elements) or for general purpose processing by user agents.
titleThis section is informative.
All these examples assume at least a surrounding <frames
xmlns="http://www.w3.org/2002/06/xframes/"> element. The
xml:id attributes have been omitted from the frame
elements for clarity.

</group><group compose="single">

<frame/>
</group>Replace "single" with "free" for moveable
frames.
An XFrames document is normally referenced by a URI reference [URI] of the form
http://example.org/home.xframes#frames(id1=uri1,id2=uri2,...).
That is to say, the part before the '#' is a URI identifying an XFrames document. After the '#' comes the word 'frames', followed by, in brackets, one or more associations separated by commas.
xframes-URI-reference = [ absoluteURI | relativeURI ] [ "#frames("
associations ")" ]
associations = association | associations "," association
association = id "=" URI-reference
Each association consists of an identifer, an equals sign, and a URI reference, with no intervening whitespace. Matched brackets within the URI reference, and commas enclosed within matched brackets, may be left unescaped; all other brackets and commas must be escaped according to URI escaping rules: %2c for comma, %28 for open bracket, and %29 for close bracket.
Each identifier in an association identifies a frame element
within the XFrames document with an xml:id attribute with that
value. The associated URI reference is then assigned to that frame. If there
is no frame with such an xml:id, the association is ignored. If there is more than one association for the same xml:id, the textually last one is used.
If a frame within the document is not populated (because it has no
xml:id attribute, or because there is no association that uses its
id), and it has a source attribute, the URI reference in that
attribute is used instead. If an unpopulated frame has no source
attribute, the frame is left blank.
An XFrames document may also be referenced with an unadorned URI (i.e.,
not a URI reference), such as http://example.org/home.xframes,
in which case the frames are populated only using the source attributes where
present.
Relative parameter URIs are interpreted relative to the XFrames document,
taking into account any xml:base [XMLBASE] value on the frames
element; relative URIs in source attributes are interpreted
according to any xml:base attributes on enclosing elements, and
otherwise relative to the XFrames document.
Having associated URIs to the frames, the XFrames document is displayed accordingly.
For example, in a document home.xframes, describing the
following layout
------- | | | |---| | | | | -------
as
<group compose="horizontal">
<group compose="vertical">
<frame xml:id="one"/>
<frame xml:id="two"/>
</group>
<frame xml:id="three" source="main.xml"/>
</group>and populated as follows
home.xframes#frames(one=a.xhtml,two=b.xhtml,three=c.xhtml)the frames would be populated by assigning a.xhtml to the
frame with xml:id="one", b.xhtml to the frame with
xml:id="two", and c.xhtml to the frame with
xml:id="three":
------- | a | | |---| c | | b | | -------
Populated as follows:
home.xframes#frames(one=a.xhtml,two=b.xhtml)the frame with xml:id="three" would be populated with
main.xml.
Populated as follows
home.xframes#frames(one=a.xhtml)the frame with xml:id="two" would additionally be left blank.
Populated as follows:
home.xframes#frames(four=nav.xml)the frames with xml:id="one" and xml:id="two" would be
blank, and the frame with xml:id="three" would be associated with
main.xml (and nav.xml would be ignored); this is
identical to populating it with the unadorned URI
home.xframes.
If a document assigned to a frame contains hyperlinks, and one of these is activated by some means (such as by the user clicking on it), then the URI of that hyperlink is normally assigned to the frame instead, and the XFrames document is redisplayed.This changes the URI associated with the XFrames document, by adding or replacing an association between the frame and the URI for the frame document; this would normally be visible to the user. If the frame containing the document does not have an xml:id attribute, so that such an association is not possible, the entire frameset is replaced by the linked-to document.
If the hyperlink is in some way targetted (for instance by being
associated with a target attribute in XHTML 1.0 [XHTML]), then in the containing frameset a frame with
an xml:id equal to the target is located, and the URI is associated
with that frame instead. If the current frameset contains no such
xml:id, but the frameset is associated with a frame in another
frameset, then the process continues with that frameset, and so on. If no
matching xml:id is found, then the targetted resource is processed
in an entirely new environment with that target identifier (for instance, a
visual browser might open a new window).
Styling, positioning, and sizing of frames is done using a style sheet in
CSS or some other suitable styling language. This means that there is nothing
normative in the values of the compose attribute except a
suggestion on how they should be rendered, and a default composition in the
absence of other styling information.
In the absence of other styling information, the height of a row is the height of its highest directly contained element; the height of a column is the sum of the heights of its directly contained elements.
In the absence of other styling information, the width of a column is the width of its widest directly contained element; the width of a row is the sum of the widths of its directly contained elements.
In the absence of other styling information, the height and width of a frame is either obtained from the intrinsic dimensions of the framed content (such as an image), or otherwise by sharing the available space equally over such undimensioned elements at the same level (so in a column of three frames, each frame is allocated one third of the height of the column; with a column of two frames and a row, the row is still allocated one third of the height of the column, even if the row itself contains more columns; in a column of three frames where one frame has been assigned a height, the remaining space is divided over the other two frames).
Note that any stylesheet in an XFrames document has no effect on the contents of any frame.
This specification does not require conformant XFrames user agents to accept or refuse any particular type of document for assignment to a frame, though it must accept at least one.
This appendix is normative.
