Well, yes, but there are issues such as these in the specs:

1) RFC3920bis-09: "for historical reasons MAY accept only the 'stream:' 
prefix"
2) RFC3921bis-08: "The <show/> element MUST NOT possess any attributes." 
(also with <status/>, <priority/>, <body/>, <subject/>)

The latter could be made to state "MUST NOT possess any non-namespaced 
attributes".

xml:lang can be supported without namespace awareness--the original XML 
spec (before XML Namespaces) allows, without reservation, the colon in 
an XML Name (as in an attribute), but according to the above issues, an 
implementation could theoretically (if not actually) use a parser which 
rejects any attributes on such elements.
