One Czech XML guru suggest me use for this "profiling". For more
information see:

http://www.sagehill.net/docbookxsl/Profiling.html

An example:

<para os="windows">WinText</para>

and when you apply XSL template you can use template with "profile-"
prefix (profile-docbook.xsl, profile-chunk.xsl) and define option
profile.os="windows".

The other thing are INCLUDEs, I think best way is use W3C's <xinclude>.
The "xsltproc" support it (--xinclude option) and for others tools
which doesn't support it you can use common tool "xmllint" that merge
all to one temporary file:

xmllint --xinclude --postvalid book.xml tmp.xml
fop -xsl /path/file.xsl -xml tmp.xml -pdf book.pdf
rm -f tmp.xml
