Proposed text:

       <t>This currently leaves signers and assessors with the potential for
         making different interpretations between the two identifiers and may
         lead to interoperability problems. A signer could intend one to be
         used for reputation, and have a non-reputation intent in setting the
         value in the other. However the assessor might choose the wrong value
         and produce an unintended (and inaccurate) reputation assessment.</t>

       <t>This update resolves that confusion.  It defines additional, 
semantic
         labels for the two values, clarifies their nature and specifies their
         relationship.  More specifically, it clarifies that the identifier
         intended for reputation lookups (such as white lists) by the
         assessor is the value of the "d=" tag. However, this does not
         prohibit message filtering engines from using the "i=" tag, or any
         other information in the message header, for filtering decisions. 
</t>

       <t>For signers and assessors that have been using the i= tag for
         reputation assessment a software change to using the d= tag is 
intended.
       </t>

This clarifies what is the primary identifier that signers 
intend to send to assessors.

If it helps to avoid stepping on sensitive toes, you could drop
the last sentence, but I can live with it.
