you talking about me?? (actually I do have ___lots__ of such stuff as
the output from my xquery to xslt translator, as basically that's the
way xquery works, with selection and node generation much more closely
intertwined than usual in xslt.

I don't think you can possibly give a warning about empty templates; it's
a very common design idiom: If you are trying to prune a tree, start off
with the identity template then add empty templates to lop off branches.
this I do _by hand_ all the time. Looking in my standard working
directory (for real code not sample answers as posted here)

$ grep "<xsl:template[^<>]*/>" *.xsl | wc -l

so that's at least 351 uses of this, I don't want to get warned about
those, I put them there on purpose...
