Re: [XBL] XBL 2.0 Semantic-free XML elements

The current text says:

  Similarly, XBL elements (other than the xbl element itself) that do
  not have a correct xbl element as an ancestor are in error too, and
  UAs must ignore them, treating them as they would any arbitrary
  semantic-free XML element.

but some UAs don't ignore such elements.  For example, when you give
Firefox a document with only semantic-free elements, it displays the
document tree.  Perhaps the text should say something to the effect that
they should not have the regular XBL processing?

Also, should such in-error XBL elements still implement the relevant XBL
DOM interface?  I think it's problematic for elements to gain and lose
interfaces if they are moved about the document.

Thanks,

Cameron
