Agreed.  I arbitrarily chose to default to the null separator for two

1. because RDF does it, and it's the only Recommendation that has
   anything to say about the specifics of concatenation; and

2. to stay out of any religious wars against which character should be 
   used as the separator.

The RDF concatenation does lead to nasty problems, as John suggests.
I could live with [space], if everyone promises not to flame me (it's
one character that's virtually guaranteed not to be allowed in XML
names in any future version of the spec).

All the best,
