RE: [xsl] Grouping problem

However, in Saxon's case, the warning might not be true, as 
Saxon allows extension functions to have side effects, so if 
one were present in the select attribute, it might indeed 
have an effect.

Or rather: the user might expect it to have an effect, but it wouldn't have
any effect, because an empty for-each is optimized away; so all the more
reason for a warning.
