The WICD Full profile is designed to enable rich multimedia content on desktop and high capability handheld agents. These are agents with:
Agents, conformant to WICD Full 1.0, MUST implement WICD Core 1.0 and CDR Framework 1.0. Agents implementing WICD Full 1.0 MUST also support WICD Mobile 1.0 that is a subset of WICD Full 1.0.
The image below shows the relation between WICD and CDF documents.
Comformant WICD Full 1.0 user agents MUST support XHTML 1.1 - Module-based XHTML as root document.
Conformant WICD Full 1.0 user agents MUST support ECMAScript 3rd Edition as a scripting language.
Comformant WICD Full 1.0 user agent MUST support Cascading Style Sheets, level 2 revision 1 CSS 2.1 Specification.
Comformant WICD Full 1.0 user agent MUST support Scalable Vector Graphics (SVG) Tiny 1.2 Specification while referenced from XHTML.
The comformant user agent MUST support JPEG/JFIF [JPEG][JFIF] and PNG [PNG] raster image formats. Other image formats MAY be supported in addition. For JPEG, the subset defined in [SVG12] SHALL be supported. For PNG, all color types and bit depths SHALL be supported, gamma correction SHALL be supported, and any alpha or transparency information SHALL be used to composite the image onto the background.
Audio MAY be incorporated into WICD Full 1.0 content in several ways. It MAY be pointed to from an XHTML object element, or an SVG audio element, or indirectly from an SVG video element where the video includes audio.
In XHTML, there are no timing elements. Thus, audio will play from the time the document is loaded until the time the document is unloaded (eg, replaced by another document as a result of following a link). In conforming WICD Full 1.0 content, audio referenced from an XHTML object element MUST have width and height of zero.
In SVG, audio MAY be triggered by user interaction or by animations to start, stop, or change volume.
For accessibility, conforming WICD Full 1.0 user agents MUST profile the option of switching off audio. [UAAG].
Some audio formats MAY be mandated in this profile. Any audio format supported by the device MUST also be supported to be used with the <audio> element in SVG and <object> element in XHTML.
Video MAY be incorporated into WICD Full 1.0 content in several ways. It MAY be pointed to from an XHTML object element, or an SVG video element.
In XHTML, there are no timing elements. Thus, video will play from the time the document is loaded until the time the document is unloaded (eg, replaced by another document as a result of following a link).
In SVG, video MAY be triggered by user interaction or by animations to start, pause, rewind, or stop.
For accessibility, conforming WICD Full 1.0 user agents MUST provide the option of pausing, rewinding, or stopping video.
Some video formats MAY be mandated in this profile. Any video format supported by the device MUST also be supported to be used with the <video> element in SVG and <object> element in XHTML.
Comformant WICD Full 1.0 user agents MUST support Document Object Model (DOM) Level 3 Core Specification and Document Object Model (DOM) Level 3 Events Specification.
The terms used in this document are specified in CDR Framework 1.0.
This specification defines conformance for several classes of products:
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 (see ). However, for readability, these words do not appear in all uppercase letters in this specification.
At times, this specification recommends good practice for authors and user agents. These recommendations are not normative and conformance with this specification does not depend on their realization. These recommendations contain the expression "We recommend ...", "This specification recommends ...", or some similar wording.
WICD Full 1.0 Document Conformance:
A conforming document must conform to CDR Framework 1.0, WICD Core 1.0 and WICD Full 1.0.
A conforming root document must be a XHTML document.

WICD Full 1.0 User Agent Conformance:
A comformant user agent MUST support all previously described comformant content.
A conformant user agent MUST implement all of the three following specification: CDR Framework 1.0, WICD Core 1.0 and WICD Full 1.0.

WICD Full 1.0 authoring is the similar than authoring any other XHTML, CSS, and SVG based content except that comformant user agents are guaranteed to show this content properly together. Therefore, authors are encouraged to take advantages of each individual languages while designing content.
To enable largest possible audience for the content, authors should make content scalable and test it with different sizes of windows and screens. All WICD Full 1.0 user agents have same visualization capabilities, but the physical screen sizes (and their resolutions) may differ a lot.
