Since the original question involved the reduction of dependency on
paths and required a single stylesheet with the import precedences
converted to priorities, I'd say my reply here is slightly off-topic,
but I'd like to chime in while Abel has brought up the subject.
I use a type of single-file stylesheet collection system, nearly
identical to what Abel defines below, in a personal project of mine. My
intentions are slightly different, simply to reduce common aspects of
the small perfunctory stylesheets to a single instance. Instead of
Xpointer, though, I use a PHP function that performs a transformation on
the collection-file which:
- adds the xsl version attribute (limited to 1.0 via libxslt right now)
- copies any namespace nodes from parent elements
- adds an xsl:import of a common.xsl file of frequently-used templates.
It does save plenty of space and clutter (especially routine
declarations like xmlns:xsl), and ensures I can rely on the common
templates being present in the collection's stylesheets. The
transformation that picks out the requested stylesheet is fairly simple;
it just takes in an "id" parameter and looks for the first child of the
root node that has the same ID. (I'm using a few literal-result element
stylesheets, so it's not limited to xsl:stylesheet children.) If
anyone's interested, I could post the stylesheet and the particular
collection I'm using, but we should split off the topic at that point.

It really shouldn't be too hard to make a structure something like the
following, which is basically a simple collection framework for
stylesheets and can internally be gathered into a set of compiled
stylesheets:
<col:stylesheet-collection xmlns:col="http://stylesheet-collection";
start-with="main">
<xsl:stylesheet col:name="main".... >
<xsl:import href="#import-me" />
</
<xsl:stylesheet col:name="import-me">
<xsl:output ... />
<xsl:template match="...
</
</col:stylesheet>
Or something like that. What catalogs are to XML and DTD, can stylesheet
collections be for XSLT. Perhaps a new standard ;)
