It seems to me that in SPARQL the metadata is in the Service 
Description; ie available via a different protocol.

Are SPARQL 1.1 end points required to allow you to query their SD by 
providing their SD address (ie their endpoint address) as the URL in a 
FROM or FROM NAMED expression?   If not, do you expect many to implement 
that?
