Extensible Stylesheet Language (XSL) Version 1.0 Errata

Replace:

the last two paragraphs

with

An area A begins an area P if A is a descendant of P and P and A have either a block-stacking constraint or an inline-stacking constraint, provided that no descendant of P which is an ancestor of A has a space-before (in the case of a block-stacking constraint) or a space-start (in the case of an inline-stacking constraint) whose computed minimum, maximum, or optimum values are nonzero. In this case the second of the adjacent edges of P and A is defined to be a leading edge in P. A space-specifier which applies to the leading edge is also defined to begin P.

Similarly, An area A ends an area P if A is a descendant of P and A and P have either a block-stacking constraint or an inline-stacking constraint, provided that no descendant of P which is an ancestor of A has a space-after (in the case of a block-stacking constraint) or a space-end (in the case of an inline-stacking constraint) whose computed minimum, maximum, or optimum values are nonzero. In this case the first of the adjacent edges of A and P is defined to be a trailing edge in P. A space-specifier which applies to the trailing edge is also defined to end P.

Replace:

the text for space-resolution rule 1.

with

If any of the space-specifiers in S' is conditional, and begins a reference-area or line-area, then it is suppressed, which means that its resolved space-specifier is zero. Further, any conditional space-specifiers which consecutively follow it in the sequence are also suppressed. For purposes of this rule, a space-specifier U consecutively follows a space-specifier V if it U follows V and U and V are separated in the sequence only by conditional space-specifiers and/or space-specifiers whose computed minimum, maximum, and optimum values are zero.

If a conditional space-specifier ends a reference-area or line-area, then it is suppressed together with any other conditional space-specifiers which consecutively precede it in the sequence. For purposes of this rule, a space-specifier U consecutively precedes a space-specifier V if it U precedes V and U and V are separated in the sequence only by conditional space-specifiers and/or space-specifiers whose computed minimum, maximum, and optimum values are zero.

Replace:

all occurrences of "float-displace"

with

"intrusion-displace"

Replace:

the text of item 4

with

Forced line-breaks are respected. Specifically, if C is a descendant of F, and C is a fo:character whose Unicode character is U+000A, and A is the area generated by C, then either C is a child of F and A is the last area in a subset S_i, or C is a descendant of a child C' of F, and A ends (in the sense of 4.2.5) an area A' returned by C', such that A' is the last area in a subset S_i.

Replace:

the text of item 5

with

The partition follows the ordering of the area tree, except for certain glyph substitutions and deletions. Specifically, if B₁, B₂, ..., B_p are the normal child areas of the area or areas returned by F, (ordered in the pre-order traversal order of the area tree), then there is a one-to-one correspondence between these child areas and the partition subsets (i.e. n = p), and for each i,

· S_i consists of a single block-area and B_i is that block-area, or

· S_i consists of inline-areas and B_i is a line-area whose child areas are the same as the inline-areas in S_i, and in the same order, except that where the rules of the language and script in effect call for glyph-areas to be substituted, inserted, or deleted, then the substituted or inserted glyph-areas appear in the area tree in the corresponding place, and the deleted glyph-areas do not appear in the area tree. For example, insertions and substitutions may occur because of addition of hyphens or spelling changes due to hyphenation, or glyph image construction from syllabification, or ligature formation. Deletions occur as specified in (6.), below.

Replace:

in the third paragraph "the normal and/or anchor inline-areas returned by the child formatting objects,"
