NEW ISSUE: SeqAck - None and Final

[Doug Davis <dug@us.ibm.com>]

Title: SeqAck - None and Final

Description:  In [1] current schema
and pseudo schema doesn't allow None and Final on the same SeqAck - and
they should be.

Justification: Its possible that a sequence
could be closed w/o any Acks.

Target: core

Proposal: Make schema and pseudo schema
support None and Final - like this:

<wsrm:SequenceAcknowledgement ...>
  <wsrm:Identifier ...> xs:anyURI </wsrm:Identifier>
    [ [ <wsrm:AcknowledgementRange ...
          Upper="xs:unsignedLong"
          Lower="xs:unsignedLong"/>
*
        | <wsrm:None/> ]
        <wsrm:Final/> ?
      | <wsrm:Nack> xs:unsignedLong
</wsrm:Nack> + ]
    ...
</wsrm:SequenceAcknowledgement>

Note: changed the + to a * on the AckRange
element. since Final can appear w/o any AckRanges.
