I see - effectively an ID at the XML syntax level (allowing serialisation of
graphs within a document) and not at the RDF model level (i.e. not an RDF
resource identifier).  Ok.

The interpretation is different.
An RDF parser should be allowed to *change* the name
by a one to one mapping in the first case. Of course it should not
be allowed to do this with URI's given by rdf:IDs.

For example the following 'RDF' would be

<rdfs:Class rdf:ID="MyClass"> 
    <rdf:Description rdf:anonymous_ID="1">

<rdfs:Class rdf:ID="MyClass"> 
    <rdf:Description rdf:anonymous_ID="2">

since there is an obvious bijection ;-).
