I've adjusted to the idea of immutable variables, but still find the lack of compound data structures frustrating. I was trying to think of a sensible way of using immutable compound data structures when I realised that in XSLT terms it would simply be a matter of allowing result tree fragments to be used as expression inputs. (I say "simply" without having thought it through - would this be tricky to design / implement?) Francis. XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
