I think it's basically to do an xsl:choose. However, your note reminded me
to add "apply-templates on atomic values" to the candidate requirements list
for future XSLT versions. It's a little hard to come up with really
convincing use cases, but I think it would make the language more orthogonal
and that's always a good thing. Certainly, polymorphism on atomic values as
well as on nodes seems intrinsically desirable.
