Subject: Core spec, new signals
and Schema





The current ebMS schema is designed so that any new
SignalMessages must be from a different namespace than messaging target
namespace [1].



So one design is just to extend “SignalMessage” with
some elements defined in ebBP signal namespace for signed receipt
acknowledgement. [2]



The element, NonRepdudiationInformation, would be the
easiest to re-use.



The resulting Messaging element would look something like:



<ebms:Messaging xmlns:ebms="http://www.oasis-open.org/committees/ebxml-msg/schema/msg-header-3_0.xsd"

   
xmlns:ebbpsig="http://docs.oasis-open.org/ebxml-bp/ebbp-signals-2.0"

   
xmlns:ds="http://www.w3.org/2000/09/xmldsig#">

    <ebms:SignalMessage>

       
<ebms:MessageInfo>

           
<ebms:TimeStamp> date time value</ebms:TimeStamp>

           
<ebms:MessageId>uiwtoruiopwr2543890@b.example.com</ebms:MessageId>

           
<ebms:RefToMessageId>uiopfdsmnf4898965563434@a.example.com</ebms:RefToMessageId>

           
<ebbpsig:NonRepudiationInformation>

               
<ebbpsig:MessagePartNRInformation>

                   
<ebbpsig:MessagePartIdentifier> </ebbpsig:MessagePartIdentifier>

                   
<ds:Reference> all the ds reference stuff</ds:Reference>

               
</ebbpsig:MessagePartNRInformation>

               
<ebbpsig:MessagePartNRInformation>

                   
<ebbpsig:MessagePartIdentifier> </ebbpsig:MessagePartIdentifier>

                   
<ds:Reference> all the ds reference stuff </ds:Reference>

               
</ebbpsig:MessagePartNRInformation>

           
</ebbpsig:NonRepudiationInformation>

       
</ebms:MessageInfo>

    </ebms:SignalMessage>

</ebms:Messaging>
