<para>This is technical reference documentation for the

miscellaneous utility 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 utility templates don’t import or include any DocBook
|
||
XSL stylesheet parameters, so the utility 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

|

<para>The <function>log.message</function> template is a utility
|
||
template for logging/emitting formatted messages – that is,
|
||
notes and warnings, along with a given log “level” and an
|

identifier for the “source” that the message relates to.</para>

<para>Text to log/emit in the source field to identify the

“source” to which the notification/warning relates.
|

This can be any arbitrary string, but because the

||
message lacks line and column numbers to identify the
|
||
exact part of the source document to which it
|
||
relates, the intention is that the value you pass
|
||
into the <literal>source</literal> parameter should
|
||
give the user some way to identify the portion of
|
||
their source document on which to take potentially
|
||
take action in response to the log message (for
|
||
example, to edit, change, or add content).</para>
|
||
<para>So the <literal>source</literal> value should be,
|

for example, an ID, book/chapter/article title, title

of some formal object, or even a string giving an

XPath expression.</para>

it is right-padded out to
