Hi Bernardo, others,

As I understand it, the (tractable) fragments document is to describe  
fragments of the whole of OWL 1.1 and not OWL 1.1 DL only. Perhaps it  
would be a good idea to include a pointer to some of the other  
proposed fragments (RDFS 3.0 and OWLPrime). We could even include some  
short description of these, with a note explaining that although they  
are already used in practice, they will be included in the tractable  
fragments document once their formal and computational properties are  
fully understood.

Perhaps we could (re)organise the document in such a way that we  
reserve a section for DL-related issues, and a section about the  
others, with a note explaining that it is our intention that these  
will be harmonised.

Best,

	Rinke
