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

[Todd Tillinghast]

Patrick,

I am thinking of a signature that is within the document but nicely
placed within the <work> element.

Exactly the same signature that is held within the "this" <work> element
could be used in a <work> element used with a reference to specify and
ensure a specific document.  This would add the features of an XML
signature to the set Dublin Core elements.  

The downside is that a reference to kjv:Esth.1.1 that uses a signature
would only be valid to the exact document that was signed.  Thus an OSIS
document of only the book of Esther was available, it would not be a
match if the signature for all 66 books.  However, using XPath within a
signature a signature for only the book of Esther could be created and
used.

More on this after the release of 2.0.
