At the very least it effectively partitions the possible RDF concrete 
syntaxes coming out of the transform to only a few (one if you collapse 
turtle and n3) and it seems reasonable (IHMO) for a GRDDL agent to make an educated guess from that point 
(one of which could be: yes, it probably is n3/turtle).

Well I think a simple normative reference (nothing more than a link even) 
to the XSLT specification should suffice.  Really, how the 
algorithm is 'applyied' should be referred to only (within 
the appropriate location of the transformation algorithm spec: XSLT in this 
case).  Otherwise, I would think it would be enough to say that the 
result of the transformation must be a valid (syntactically) RDF Graph.
Although, you can infer that if it has to be 'an RDF Graph' then it must 
be a syntactically valid RDF serialization.
