Re: [xsl] 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.
