New version: http://www.w3.org/2001/sw/RDFCore/errata#rdf-syntax-grammar

Incorporating Graham's qualifier, a typo fix from Pat Hayes, and a
closing observation I could do with someone reviewing (tried to 
interpret Dave's IRC comment that this was really 2 issues...):
Serialization of datatyped empty literals is not anticipated by the
RDF/XML grammar.

This is believed by several developers and former WG-members to be an
omission in the grammar defined by the RDF/XML Syntax Specification: a
bug was reported (and acknowledged by the editor), relating to the use
of an rdf:datatype attribute on empty RDF properties. See the archived
mailing list thread for technical details. In addition to the question
of the RDF/XML grammar's syntactic completeness, note that this issue
identifies a construct that occurs within RDF graphs that cannot be
serialized in the RDF/XML syntax. 

Is that last claim right? Is there a difference btw between

<foo:prop rdf:datatype="http://www.w3.org/2001/XMLSchema#string"


	<foo:prop rdf:datatype="http://www.w3.org/2001/XMLSchema#string"/>

...in terms of this issue and the grammar productions?
