I have already decided here to change the reference to point to the
definition of RDF URI Reference as given in the RDF Concepts WD:
and say less here.  The N-Triples doc will then just describe how to
encode such things into N-Triples.

However, from what I recall of the definition of URIs, an absolute
URI reference must start with a legal URI 'scheme', therefore there
must be at least one legal 'scheme' character before the first ':';
So '::' is not a legal absolute URI (or absolute URI reference).  The
definitive answer is of course in the URI RFC and I think the BNF
section defines that answer.
