? I thought it did conform with Concepts, and which sentence are you referring to? 
I may have already made this change without realizing it, so check new wording there.

I will simply abandon the terminology "well-typed" altogether, it is too confusing and not needed.  Done.

I put it back in because I thought you wanted it there. :-)  But I agree, so...done.

?Is this necessary? I think we are OK just saying that its a datatype IRI with a value space.
