Proposed text for clarifying protocol conformance

In http://www.w3.org/2009/sparql/docs/protocol-1.1/Overview.xml#conformance

"""
A conformant SPARQL Protocol service:

   1. must implement either the query operation or the update operation 
in the way described in this document ("SPARQL 1.1 Protocol");

   2. may implement both the query and update operations;

   3. must implement all three forms of the query operation (query via 
GET, query via POST with URL-encoded parameters, and query via POST 
directly) if it implements the query operation

   4. must implement both forms of the update operation (update via POST 
with URL-encoded parameters and update via POST directly) if it 
implements the update operation

   5. must be consistent with the normative constraints on SPARQL 
Protocol services (indicated by [RFC2119] keywords) described in 4. 
Policy Considerations.

A conformant SPARQL Protocol client:

   1. must generate requests for either the query operation or the 
update operation;

   2. may generate requests for both the query and update operations;

   3. may generate requests for any or all of the three forms of the 
query operations if it generates query requests;

   4. may generate requests for either or both of the two forms of the 
update operations if it generates update requests;

   5. must be consistent with the normative constraints on SPARQL 
Protocol clients (indicated by [RFC2119] keywords) described in 4. 
Policy Considerations.

Any suggested changes or support for this?
