[ebxml-cppa] ID clash in CPA

[Peter Ogden <pogden@cyclonecommerce.com>]

I recently went through the exercise of creating two CPPs, and from them, a CPA. I noticed that anywhere in the CPP where we use an ID, we have a potential "clash" when building a CPA. For example, if both parties' CPPs contain the following element

 

<tp:Certificate tp:certiId="EncryptionCert"><ds:KeyInfo/></tp:Certificate>

 

the resulting CPA will not validate because duplicate IDs are not allowed. If both parties take care to "namespace" their IDs (perhaps with their PartyIds, e.g. "myDUNS_EnryptionCert"), this won't be a problem. If that's the solution, we should document it clearly.

 

Is this a problem, or have I missed something?
