Reading this made me realize something obvious, but previously overlooked 
(by me).
Not every URI can be used as an RDF property identifier in the RDF 
syntax.  e.g. https://acme.com/property/
The model doesn't have this restriction, that I can see, which suggests a 
mismatch between model and syntax.
Is this on the issues list?  Should it be?
