Hi again,

Just to clarify,

The function served nothing more than a pedagogical use in my solution (which was only a modification of Ken's first solution, thus not a solution at all). It wasn't necessary at all, except for the purposes of (a) showing how a function works, and (b) showing how a function, in a case like this, can expose the logic in a way that makes it a bit easier to read and interpret, as well as to modify in view of new, or changing, or newly understood requirements.

In this it's not much different from

<xsl:variable name="complicated-xpath"
  select="complicated/xpath[if exists(name)
                            then 'easier to understand']"/>
<xsl:apply-templates select="$complicated-xpath"/>

Of course I know it's only easier to read and interpret a function if one knows or can guess how functions work. (In this, a function is like a key.) But that isn't so hard, and learning how to read and interpret XSLT is part of the reason we're here.
