<para>This is technical reference documentation for the

character-map templates in the DocBook XSL Stylesheets.</para>
|
||
<note>
|
||
<para>These templates are defined in a separate file from the set
|
||
of “common” templates because some of the common templates
|
||
reference DocBook XSL stylesheet parameters, requiring the
|
||
entire set of parameters to be imported/included in any
|
||
stylesheet that imports/includes the common templates.</para>
|
||
<para>The character-map templates don’t import or include
|
||
any DocBook XSL stylesheet parameters, so the
|
||
character-map templates can be used without importing the
|
||
whole set of parameters.</para>
|
||
</note>
|
||
<para>This is not intended to be user documentation. It is
|
||
provided for developers writing customization layers for the

stylesheets.</para>

<para>This template applies an <link

xlink:href="http://www.w3.org/TR/xslt20/#character-maps"
|
||
>XSLT character map</link>; that is, it causes certain
|
||
individual characters to be substituted with strings of one
|
||
or more characters. It is useful mainly for replacing
|
||
multiple “special” characters or symbols in the same target
|
||
content. It uses the value of
|
||
<parameter>map.contents</parameter> to do substitution on
|
||
<parameter>content</parameter>, and then returns the

modified contents.</para>

<para>The XSLT 2.0 specification describes <link

attribute node in a final result tree to be substituted by

a specified string of characters during serialization. The

the value of the <parameter>use.subset</parameter>
