Didn't notice that change in the new draft, sorry. Good decision.

Ah, I have a problem there you see. I'm implementing an XForms to HTML
XSLT so in order for namespaces in the XForms to work they also need to be
present in the XSL (which is meant to be generic), and have the same
namespace prefixes (for the needed evaluate() to work)...

The following would be valid (not cheating), right?

Where is the instance() function described? It's referred to in 7.4 but
couldn't find it anywhere else in the draft. I see it has been discussed
on this list earlier along with a model()...

If anyone could confirm these I'd be grateful:


  ref="mom/son"  => 'me'
  ref="/root/mon/son"   => 'me'
  ref="/mom/son"   => invalid

BTW, there seems to be a typo in 8.1.10: "(the value='...' attribute of
the item element)". Should be "value element".
