Not to me.  As I've been pointing out before, if assertions are
expressed in a formal knowledge representation which properly
distinguishes languages from "information resources" there is no
problem.  Consider DOLCE's corresponding term for 'linguistic object':

<owl:Class rdf:about="#linguistic-object">
    <rdfs:subClassOf
rdf:resource="http://www.loa-cnr.it/ontologies/ExtendedDnS.owl#information-object"/>
    <rdfs:subClassOf>
      <owl:Restriction>
        <owl:someValuesFrom
rdf:resource="http://www.loa-cnr.it/ontologies/ExtendedDnS.owl#information-encoding-system"/>
        <owl:onProperty
rdf:resource="http://www.loa-cnr.it/ontologies/ExtendedDnS.owl#ordered-by"/>
      </owl:Restriction>
    </rdfs:subClassOf>
    <rdfs:comment rdf:datatype="http://www.w3.org/2001/XMLSchema#string"
    >An information object ordered by (encoded according to) a
language.</rdfs:comment>
  </owl:Class>

There is a *clear* (ontological) seperation between the document
(information object/resource) and the language it is encoded in.  IMO,
The bug here is with the mechanism used to conclude the nature of
http://www.w3.org/XML/XMLSchema not, the draft.

In DOLCE (see [1] & [2]) they *may* (I couldn't determine this from a
quick perusal) but at the very least, the semantics of what a document
is and a language encoding is clearly articulated.
