Gary I certainly agree with your comments about scope for 1.2, but I do not agree that Neil's proposal is equivalent to what is currently in the draft of 1.2. Under Neil's proposal, a signature would look like this,
<alert xmlns="urn:oasis:names:tc:emergency:cap:1.1">
<identifier>Test-1</identifier>
...
<Signature> <!-- Additional isolating element -->
<Signature xmlns="http://www.w3.org/2000/09/xmldsig#";>
<SignedInfo>
...
Versus the current 1.2 draft and as outlined in CAP 1.1 also,
<alert xmlns="urn:oasis:names:tc:emergency:cap:1.1">
<identifier>Test-1</identifier>
...
<Signature xmlns="http://www.w3.org/2000/09/xmldsig#";>
<SignedInfo>
...
Neil's proposal would not validate according to 1.1 nor 1.2 as currently drafted. BTW did you get a chance to try the <import> version of the schema that I sent? However as I suggested yesterday, it appears the DM-OPEN implementation difficulties stem from having the two <any> elements to support signatures and encryption right beside each other. Since most of the group is clearly agreed that encrypting a standalone CAP message is "problematic" and that encryption should be handled using EDXL or at the transport level, then a schema that supported ONLY signatures would look like this. With just a single <any> element, your DM-OPEN tools shouldn't run into any further problems.
