[osis-core] XML Signature [<signature> in <work>]

[Patrick Durusau]

Todd,

Definitely a post 2.0 issue but a couple of quick points:

1. Signing XML documents (as you know) does not require an element 
inside the document, so I am not sure of the need for the new element.

2. I think your proposal conflates two purposes for signing: A. This is 
the XML document I issued, and 2. This document is the same as some 
other document. Not sure of the benefits from #2.

Will be out for a few minutes and will then start calling to see what we 
have left to iron out.

Hope you are having a great day!

Patrick
