This is technical reference documentation for the DocBook XSL Stylesheets; it documents (some of) the parameters, templates, and other elements of the stylesheets.
This is not intended to be “user” documentation. It is provided for developers writing customization layers for the stylesheets, and for anyone who's interested in “how it works”.
Although I am trying to be thorough, this documentation is known to be incomplete. Don't forget to read the source, too :-)

Name
t:templates — Construct a stylesheet for the templates provided
Synopsis
<xsl:template match="t:templates"/>
Name
t:titlepage — Create the templates necessary to construct a title page
Synopsis
<xsl:template match="t:titlepage"/>
The t:titlepage element creates a set of templates for processing the titlepage for an element. The “root” of this template set is the template named “wrapper.titlepage”. That is the template that should be called to generate the title page.
The t:titlepage element has three attributes:
- element
-
The name of the source document element for which these templates apply. In other words, to make a title page for the article element, set the element attribute to “article”. This attribute is required.
- wrapper
-
The entire title page can be wrapped with an element. This attribute identifies that element.
- class
-
If the class attribute is set, a class attribute with this value will be added to the wrapper element that surrounds the entire title page.
Any other attributes are copied through literally to the wrapper element.
The content of a t:titlepage is one or more t:titlepage-content, t:titlepage-separator, and t:titlepage-before elements.
Each of these elements may be provided for the “recto” and “verso” sides of the title page.
Name
@* (in copy.literal.atts mode) — Copy t:titlepage attributes
Synopsis
<xsl:template match="@*" mode="copy.literal.atts"/>
Name
t:titlepage-content — Create templates for the content of one side of a title page
Synopsis
<xsl:template match="t:titlepage-content"/>
The title page content, that is, the elements from the source document that are rendered on the title page, can be controlled independently for the recto and verso sides of the title page.
The t:titlepage-content element has two attributes:
- side
-
Identifies the side of the page to which this title page content applies. The side attribute is required and must be set to either “recto” or “verso”. In addition, you must specify exactly one t:titlepage-content for each side within each t:titlepage.
- order
-
Indicates how the order of the elements presented on the title page is determined. If the order is “document”, the elements are presented in document order. Otherwise (if the order is “stylesheet”), the elements are presented in the order that they appear in the template (and consequently in the stylesheet).
The content of a t:titlepage-content element is a list of element names. These names should be unqualified. They identify the elements in the source document that should appear on the title page.
Each element may have a single attribute: predicate. The value of this attribute is used as a predicate for the expression that matches the element on which it occurs.
In other words, to put only the first three authors on the recto-side of a title page, you could specify:
<t:titlepage-contents side="recto"> <!-- other titlepage elements --> <author predicate="[count(previous-sibling::author)<2]"/> <!-- other titlepage elements --> </t:titlepage-contents>
Usually, the elements so named are empty. But it is possible to make one level of selection within them. Suppose that you want to process authorgroup elements on the title page, but you want to select only proper authors, editors, or corporate authors, not collaborators or other credited authors.
In that case, you can put a t:or group inside the authorgroup element:
<t:titlepage-contents side="recto"> <!-- other titlepage elements --> <authorgroup> <t:or> <author/> <editor/> <corpauthor/> </t:or> </authorgroup> <!-- other titlepage elements --> </t:titlepage-contents>
This will have the effect of automatically generating a template for processing authorgroups in the title page mode, selecting only the specified children. If you need more complex processing, you'll have to construct the templates by hand.
Name
t:titlepage-separator — Create templates for the separator
Synopsis
<xsl:template match="t:titlepage-separator"/>
Name
t:titlepage-before — Create templates for what precedes a title page
Synopsis
<xsl:template match="t:titlepage-before"/>
Name
* (in document.order mode) — Create rules to process titlepage elements in document order
Synopsis
<xsl:template match="*" mode="document.order"/>
This template is called to process all of the children of the t:titlepage-content element. It creates the hairy select expression necessary to process each of those elements in the title page.
Note that this template automatically handles the case where some DocBook elements, like title and subtitle, can occur both inside the *info elements where metadata is usually stored and outside.
It also automatically calculates the name for the *info container and handles elements that have historically had containers with different names.
Name
* (in document.order mode) — Create rules to process titlepage elements in stylesheet order
Synopsis
<xsl:template match="*" mode="document.order"/>
This template is called to process all of the children of the t:titlepage-content element. It creates the set of xsl:apply-templates elements necessary process each of those elements in the title page.
Note that this template automatically handles the case where some DocBook elements, like title and subtitle, can occur both inside the *info elements where metadata is usually stored and outside.
It also automatically calculates the name for the *info container and handles elements that have historically had containers with different names.

Name
