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>

to allow a specific character appearing in a text or

attribute node in a final result tree to be substituted by

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