RE: Receipt Request Attribute

My opinion on this would be:

1.  A CounterSignature can contain a receipt request.
2.  The receipt request on the original SignedData and the receipt receipt
on the CounterSignature can be different.  The requirement is that all
receipt requests in a SignerInfo sequence be the same and a CounterSigner
has a different SignerInfo sequence

I would appreciate clarification on the following with respect to the
Receipt Request attribute:

1.      May a CounterSignature contain a receipt request?

2.      If so, MUST all receipt requests in a SignedData be identical?  The
spec specifies that all Receipt Requests be identical.  Is it the intent
that CounterSignatures containing a receipt request MUST also be identical
with other receipt requests if it exists?  I don't see why each
countersignature can not have a different receipt request.
