It was the wording of internal subset vs internal entity that got me I 
think.  Section 4.5 does not distinguish between internal entities in 
the internal subset and those external to the xml file.  However its 
instructions must be modified by the "PEs in internal subset" 
constraint from section 2.8.

Following through the grammer this is clear but the text in Section 4.5
is not.  

Do you know why there is the restriction on PEs in internal subsets.  
It does make non-validating parser's easier I guess since they aren't 
required to read external entities.

Thanks for the tweak in the right direction.
