Requirements for XSL Extensions

The axf:outline-expand specifies whether to display the lower hierarchy of bookmark items or not.

True specifies to display the lower hierarchy in the expanded state. False specifies to display in the collapsed state.

The axf:outline-group groups bookmark items, and outputs them collectively.

If this property is omitted or specifies empty string, bookmark items are not grouping. If this specifies any string, the string is used as the name of group. The group with the same name is outputted collectively.

The axf:outline-level indicates the hierarchy level of bookmark items.

The <number> must be non-negative integer. Initial value is zero and it means that bookmarks should not be created. The highest level of bookmarks is 1 and it becomes 2 or more according to the hierarchy level of the bookmarks.

The axf:outline-title specifies the string which is appeared as a title of bookmarks.

If this property is omitted or this has empty string, the text of the object to which the property is added will become the title.

The axf:footnote-position specifies the method to layout the footnote.

Values have the following meanings.

page

Footnotes are layouted at after side of each page in region-body. This is the standard layout of XSL 1.0 specification.

odd-page [-]

Footnotes are layouted at after side of each odd-page in region-body.

start-side [-]

Footnotes are layouted at each page in region-start.

end-side [-]

Footnotes are layouted at each page in region-end.

inside-side [-]

Footnotes are layouted at each even-page in region-end and each odd-page in region-start.

outside-side [-]

Footnotes are layouted at each even-page in region-start and each odd-page in region-end.

column

Footnotes are layouted at after side of each column.

inside-column [-]

Footnotes are layouted at after side of the last column of even-page or the first column of odd-page.

outside-column [-]

Footnotes are layouted at after side of the first column of even-page or the last column of odd-page.

page-sequence [-]

Footnotes are layouted at the end of page-sequence.

document [-]

Footnotes are layouted at the end of the document.

Specifies whether to omit the same footnote.

Suppresses the duplicated footnotes in the same footnote area, when the same footnote is allocated in two or more places.

The axf:revision-bar-color specifies the color of the revision bar.

The axf:revision-bar-offset specifies the offset of the revision bar.

Values have the following meanings.

start

Places revision bar at start-edge.

end

Places revision bar at end-edge.

inside

Places revision bar at start-edge on odd pages, at end-edge on even pages.

outside

Places revision bar at end-edge on odd pages, at start-edge on even pages.

alternate

Places revision bar at end-edge in the last column of multi-column layout, except for the last column, places it at start-edge.

both

Places revision bar at start-edge and end-edge.

The axf:revision-bar-style specifies the style of the revision bar.

The axf:revision-bar-width specifies the width of the revision bar.

The axf:column-rule-align specifies the alignment of the column rule.

These are not present in CSS3 Multi-column layout.

The axf:column-rule-color specifies the color of the column rule.

These are not in CSS3 Multi-column layout.

The axf:column-rule-style specifies the style of the column rule.

See CSS3 Multi-column layout.

The axf:column-rule-width specifies the width of the column rule.

See CSS3 Multi-column layout.

The axf:background-color sets the background color of fo:simple-page-master.

The axf:background-image sets the background image of fo:simple-page-master.

The axf:physical-page-number gets physical page number.

The value of initial-page-number property is disregarded and the physical page number that is not affected by page-sequence is obtained. In order to obtain the total number of pages, ID is given to the last page, and it is performed as follows.

<fo:page-number-citation ref-id="lastpage" axf:physical-page-number="true"/>

The axf:suppress-duplicate-page-number specifies to delete the duplicated page numbers.

When formatting a index, generally several fo:page-number-citation line up for one index item. In such case, when fo:page-number-citation refers to the same page number of the index, page numbers are output repeatedly using the standard property.

contextual

Adjacent full width punctuation characters are treated to trim.

• Between full width close parenthesis and non punctuation characters.
• Between full width open parenthesis and full width open parenthesis.
• Between full width middle dots and full width open parenthesis.
• Between non punctuation character and full width open parenthesis.

Full width punctuation characters are treated the same as full width close parenthesis.
The space between full width close parenthesis and non punctuation characters is not condenced pnly by specifying axf:kerning-mode="contextual". The space can be condenced by setting the value of axf:punctuation-spacing less than the default.

auto

This is depended on system setting.

The font size of the pair kerning is specified. This property is based on CSS3 Text Module: 8.5. Text kerning.

When auto is specified, it is pair kerning (axf:kerning-mode="pair") regardless of the size. When "length" is specified, the pair kerning is done if it is larger than the size.

The axf:line-break specifies the method of line breaking. This property is based on CSS3 Text Module: 6.2. Line breaking.

Values have the following meanings.

The axf:line-break-at-punctuation-in-word specifies the controls of the line breaking after the symbols in the alphanumeric characters.

Values have the following meanings.

loose

This is depended on UAX#14: Line Breaking Properties.

normal

It becomes hard to break lines between the alphabetic characters and the symbolic characters classified as IS. The other symbolic characters conforms to UAX#14. Originally, the line breaking between the symbols and the numeric characters is prohibited by UAX#14.
When the alphanumeric string before and after the IS symbolic characters is relatively long and is not hyphenated, the line breaks after the IS symbolic characters. When the string is short, the line does not break actively because of the possibility of the abbreviation.

restrict

It becomes hard to break lines between the symbols and the alphanumeric characters. When the alphanumeric string before and after the symbols is relatively long and is not hyphenated, the line breaks after the symbols. When the string is short, the line does not break actively because of the possibility of the abbreviation.

strict

Prohibits the line breaking between symbolic characters and the alphanumeric characaters.

auto

This is depended on system setting.

Symbolic characters described here means the characters that belong to the following character class in UAX#14. Line breaking between the symbolic characters and the PR Prefix (Numeric) is prohibited according to UAX#14.
