Hi,

 From css3-namespace:

> CSS qualified names can be used in (for example) selectors and
> property values as described in other modules. Those modules must
> define handling of namespace prefixes that have not been properly
> declared. Such handling should treat undeclared namespace prefixes as
> a parsing error that will cause the selector or declaration (etc.) to
> be considered invalid and, in CSS, ignored.


css3-values uses qualified names in attr(), but does not define the 
error handling for undeclared prefixes. (Or did I miss it?)

Proposed change: in the list after "The attr() expression is only valid 
if", add an item:

  # The attribute name is not qualified with an undeclared
  # namespace prefix.

(I don’t like the double negation, but I can’t find a better wording for 
now.)
