I was reviewing the Mail archive with a view to understanding how to go
about creating References that "point" to sub elements within a
Document:
<message>
<Header> The Header
</Header>
<Body>The Body
</Body>
</message>
so I expected to be able to create a Signature Reference Element using
something like
sig.addDocument("#xpointer(//Header)");
Reviewing the archive I see that
a) If I'm not using an ID attribute I don't seem to able to do this. Is
this true even if I have a schema for the document?
b) I can do this using XPath transforms.
My problem is that I am following a set of guidelines which state
a) That I should reference the "Header" and "Body" separately in my
signature
b) That I should not use Transforms ( apart from the normal C14N and
enveloped signature )
c) I can't depend on the document following the schema precisely ( the
organization sending the document is loose in the way it interprets the
schema.)
My Question is
"IS there any way of using the sig.addDocument("Xpointer(Xpath))"); type
syntax at all ? Or is there any planned?"
I would be quite willing to write a resolver or whatever to do this ( I
am assuming I will use Xalan/Xerces XPath engine to do the hard part ).
Thanks
