[ebxml-dev] Presence of sequenceNumber element in Response message.

[Kumar <kumar@SAMSUNGSDSINDIA.com>]

Hi! ebXML folks,
According to ebXML TRP spec "1.0" if the message is reliably sent, it
Must contain the Conversationid element which in turn has a sequence
Number element.
Consider a Situation where two Parties are exchanging some services,
example Party A and Party B

If Party A  initiates the conversation ,
then in the request message following elements appear
MessageID
ConversationID
SequenceNumber

Now the 
Party B responds to Party A  , while responding wether the Sequence
Number element must be present or not. If present wether it can be
incremented on the response end.
