Well, this could be handled by an exsl:slice() function:

exsl:slice($nodes, 1, 5)

Would return the first 5 nodes of $node, using the same ordering as used by 
<for-each select="">

I personally think that broad node-set operators would make up a more general 
facility than an "append-only-to-the-result" facility.
