Thanks for that reminder... xsl:for-each-group and regular expressions are
well settled in my XSLT2 mind-set, but xsl:sequence is more or less ignored.

Yes, if...

I still try to find the best balance between writing some complex, possibly
hard to debug multi-line XPath expressions or a tree of XSLT elements. Haven't
found a general rule for that, and maybe there isn't.
