Aw, fiddle. You guys showed me how to collect items with variables, too.

If you need to find the items with @group != 0 frequently, use a global
variable:
<xsl:variable name="nonzeroitems" select="//item[(_at_)group != 0]"/>
If you don't need them frequently, then you don't need a key.
If "0" is actually a variable, then a key isn't going to help.
