Re:  nested grouping problem
Thanks for the simple solution, David. I am mystified as to how the<xsl:if test="position()!=1">;</xsl:if> knows to put the semicolon after every grouped @main item except the last one. I would think it wouldn't place one after the first item in the group.

This is going to become an important idiom for streaming, and is probably worth adopting generally. Instead of putting a comma after every item except the last, put one before every item except the first. The reason is that you always know whether the current item is the first, but you don't know whether the current item is the last without lookahead.
