- <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>The XSLT 2.0 specification describes <link

- >character maps</link> and explains how they may be used
- to allow a specific character appearing in a text or
- attribute node in a final result tree to be substituted by
- a specified string of characters during serialization. The
- <function>read-character-map</function> template provides a
- means for reading and using character maps with XSLT
- 1.0-based tools.</para>
- <para>This template reads the character-map contents from
- <parameter>uri</parameter> (in full or in part, depending on
- the value of the <parameter>use.subset</parameter>
- parameter), then passes those contents to the
- <function>apply-character-map</function> template, along with
- <parameter>content</parameter>, the data on which to perform
- the character substitution.</para>
- <para>Using the character map “in part” means that it uses only
- those <tag>output-character</tag> elements that match the
- XPath expression given in the value of the
- <parameter>subset.profile</parameter> parameter. The current
