[ebxml-cppa] editorial comment on V2

I just came across the following minor editorial and schema problem with
the CPA Signature element.  Lines 3152-3155 state:

The Signature element, if present, is made up of one or more ds:Signature
elements. In a CPA involving two Parties, there can be up to three ds:
Signature elements within the Signature element. The CPA is initially
signed by one of the two Parties. The other Party could then sign over the
first Party!/s signature. The resulting CPA MAY then be signed by a notary.

Since a CPA can never involve only one Party, that goes without saying
(second sentence). Also, if the Signature element is present, there can be
either 2 or 3 ds:Signature elements, never only one unless we want to allow
for signing by only one Party.  I suggest fixing the schema to specify a
cardinality of minOccurs="2" maxOccurs="3", and changing the paragraph to:

The Signature element, if present, is made up of two or three ds:Signature
elements. The CPA is initially signed by one of the two Parties. The other
Party then signs over the first Party!/s signature. The resulting CPA MAY
then be signed by a notary.

If the team prefers to keep open the option of signing by only one Party,
then no change is needed to the schema and the paragraph would be as
follows:

The Signature element, if present, is made up of one to three ds:Signature
elements. The CPA can be signed by one or both Parties. It is RECOMMENDED
that both Parties sign the CPA. For signing by both parties, the first
Party signs. The other Party then signs over the first Party!/s signature.
The resulting CPA MAY then be signed by a notary.


Regards,
Marty
