I disagree, according to what I read in "Namespace for XML" which
specifically points to the XML specification's attribute section,
it says in "3.3.2 Attribute Defaults":

  "...; the #FIXED keyword states that the attribute must always have
   the default value..."

So I read that as meaning that when you use #FIXED in an attribute
declaration, then you *must* place the attribute in your document 
*and* that attribute *must* contain the same value as defined in 
the attribute declaration.

Thus, the documents in question fail that test since they omit the
attribute and is why, I believe, that the XHTML 1.0 specification
explicitly says in 3.1.1 (3) says it *must* be declared.
