As far as i can see not, unless you redefine the current() function.
Why not using the Muenchian method?

 <xsl:key name="sibling-names" match="*" use="concat(generate-id(..),'#',name())"/>

Untested. There are some obvious optimizations.

I'm not sure whether this is what the original poster wanted
but HTH anyway.

I also hope Jeni is absorbed with other stuff enough that i
can beat her this time...  :-)
