First, a heads up on my action to write a section defining the RDF
It's progressing, attached (with the usual red and green), still
unfinished, and what is done is quite rough (no consistency in term use,
or capitalization etc. I still need to do my own checking on readability

Second a few questions.

1. Are there unattached nodes in an RDF graph?

2. Can any URI ref be a property name or must there be some associated

3. For XML literals should I
   - specify that they must be well-balanced XML
   - explicitly permit any unicode string (but only constrain equality
for well-balanced XML)
   - have deliberate vagueness (e.g. talk about a unicode string, and
then only define equality on well-balanced XML and ignore the issue of
whether other strings are permitted or not).

Test cases for 1 & 2.


Is this RDF/XML document


equivalent to or different from this one:


and/or this one:

 <rdf:Description rdf:about="http://example.org/"/>

(the question can't be asked in N-triple)



whose status is pending

Is this:

a) an error because there is no such RDF graph


b) an example of alegal RDF graph that cannot be serialized as RDF/XML


and our resolution is not helpful.
