Wow, I'm new to the list and yet I think I know the answer to this
one, at least in principle.

I have in one of my style sheets the following construct:

following-sibling::element[position() &lt; 3]

This is selecting elements within 3 of the context element, so in your
case, I would imagine the 'next()' function could be accomplished
with:

following-sibling::element[position()=1]

Not tested, but it would seem to be to be the answer.  Hope it helps.
