The document is internally inconsistent on the treatment of XML Literals.

The change list in the document Semantics says that XML literals ``are now
required to be in canonical form and therefore to denote their own literal
string.''  This appears to mean that XML literals are just a subset of
character strings.  This is completely counter to what is said in RDF
Concepts, at least the version pointed to from the document.

However, Section 3 of the document Semantics has no mention of the fact
that XML literals denote themselves.  It also says that is ``is
deliberately agnostic as to whether or not XML data is considered to be
identical to a character string'', which is in direct contradiction to the
wording in the change list.

So, I do not feel that my concerns in this area have been adequately
