[xsl] XSLT 2: Best Way to Synthesize Elements Given List of Tagnames

["Eliot Kimber ekimber@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Say I have this string: "foo/bar" (or any arbitrarily-long sequence of
/-delimited tag names) and want to construct from it:

<foo>
  <bar>
    <!-- Stuff added here that I get from somewhere else -->
  </bar>
</foo>

Is there an easier or more obvious way to generate this than an recursive
function?

With a recursive function I can easily create child elements until the
sequence is exhausted but it feels like there should be an easier way
using XSLT 2 but if there is I'm not thinking of it.

Cheers,

Eliot
