I do some xsl:fo formatting that depends on the value of an element
<design-id value="design-001" />. I keep the xsl stylesheets for each
design in a separate directory 'design-001'. Currently, I import all
designs in my start xsl and then switch according to the value of the
design-id. This works but has the disadvantage that all templates,
attribute-sets etc have to be globally distinct, which I do by prefixing
them with a
design-marker, e.g. 'd001-'. This strikes me as not very elegant. What
would be a more clever way to do this?
Many aspects of XSLT stylesheet processing require everything to be known
at stylesheet writing time, including the name of every called template,
all modes, match patterns (which is why they cannot have variables), etc.
Therefore, there are no run-time methods you can take advantage of for what
you ask.
Have you considered synthesizing an included template that does as many
xsl:includes and as many xsl:whens as you have fragments? Then your
hand-authored fragment can just call the "dispatch" named template passing
the testable parameter and your synthesized fragment then dispatches to the
appropriately included fragment?
This would keep your hand-authored fragment succinct and using XSLT to
synthesize the included fragment would be a robust way of ensuring you have
no typographical errors in the references to included fragments or called
templates.
I hope this helps.
