Questions concerning namespaces module

Dear CSS WG,


please allow me two questions concerning "CSS Module:
Namespaces" [1]:

* Would "toto|A" also work without a namespace
declaration assuming that there is such an element, or would
it be ignored?

* Will the "xml" namespace become a
"default" namespace declaration meaning that you
don't need to explicitly declare it? Otherwise, could this
be (or was it) considered?


Thank you, regards,
 Jens.

If you mean whether the selector 'toto|A' would match
anything if the
prefix 'toto' has not been declared, then the answer is no.

I argued in favour of doing that, but as I understand it,
this has so
far been rejected. I certainly hope Elika is counting your
vote though.

I would hope that not only would that selector not match but
that the rule in 
question would be discarded altogether....

Yep. The Selectors spec defines this:

http://
www.w3.org/TR/css3-selectors/#typenmsp

   # A type selector containing a namespace prefix that has
not been
   # previously declared is an invalid_ selector.
   #
   # .. _invalid: http
://www.w3.org/TR/css3-selectors/#Conformance

CSS3 Namespaces can't define this (because it requires some
knowledge of
the context in which a qname is used), but makes a
recommendation that
any modules referencing it make an equivalent statement:

http:
//www.w3.org/TR/css3-namespace/#css-qnames

   # Those modules should define the use of a namespace
prefix that has
   # not been properly declared as a parsing error that will
cause the
   # selector or declaration (etc.) to be considered invalid
and ignored.
