> Here is the basic issue we have been having in building a CAP 1.2 implementation. Your help is appreciated. Neil recommends a change to CAP 1.2. I am not sure we want to do that, but we sure do need to find a way to use the "Standard FEMA SOA platform" without having to hand code everything behind the WSDL. So, suggestions are appreciated.

Neil's suggestion would entail creating Signature and EncryptedData elements as containers for the DSig and XMLEnc elements. This of course would change the schema and the specification language, a substantive change, and require a 15 day public review. I don't think this change, creating new elements, fits in the original scope for 1.2, but I had thought of creating a Security container for CAP 2.0 that could be used to hold not only the DSig and Encryption elements but other security related information for the CAP message.
I have included an alternate schema that does not require these containers but also takes a different approach than the current use of <any>. It uses imports and so therefore wasn't the first choice for 1.2 as its less portable. If this implementation problem is isolated then FEMA could use this modified schema as a workaround. The current schema using <any> does validate and works with several different parsers and libs, we'd need more feedback from a multitude of implementors before we could determine if there is indeed a problem that needs correction or is just specific to this implementation only.
Try this out and let me know,
