Hi Gregor,
I'm not sure it is appropriate to add xml:space="preserve" to all mixed
content elements. That attribute tells applications to preserve *all* white
space. Wouldn't that have the unintended consequence of preserving indents
and line breaks within a para in its formatted output? The default behavior
in XSL-FO is to collapse multiple white space characters into a single
space, giving paragraphs the nice formatted flow. If a stylesheet
encounters an element with xml:space="preserve", that should override the
default behavior if the processor were behaving correctly, no?

Subject: [docbook] xml:space or not
hi list,
this is an more philosophical thought/question. i'm tested some docbook
documents and playing with some custom xslts.
problem is indentation and strip-space.
with my xslt i need to strip all white space between non mixed content
elements.
problem with the following snippet:
<para><emphasis>em1</emphasis> <emphasis>em2</emphasis></para>
with <xsl:strip-space elements="*"/> this is transformed to:
<para><emphasis>em1</emphasis><emphasis>em2</emphasis></para>
which is obviously not what i want. with:
<para><emphasis>em1</emphasis> x <emphasis>em2</emphasis></para>
everything works fine, whitespace is preserved.
i know how to get around the limitation with:
<xsl:preserve-space elements="para"/>
in this case i have to add any mixed content element to the list, i.e.
reading the whole dtd checking/adding every element.
wouldnt it be better to add an fixed attribute to any mixed content
element like:
xml:space CDATA #FIXED "preserve"
this would help not only with xslt transformation also with pretty print
functions (assumed the dtd is interpreted). and would make clear how to
handle the current element.
i'm not assuming that this is added in near future, i would be more
interested if this idea was discussed. and/or if this method causes any
problems with custom dtds.
hope this question is fitting into the list topic!
all the best,
gregor
