<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>

<para>This is not intended to be user documentation. It is
|

|

provided for developers writing customization layers for the

stylesheets.</para>

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 message-level field to

|
<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>
