In my application, the data being signed can be quite large (1MB and more),
even though most may only be 100-250k range.  The ThreeSignerContract
sign/verify examples are quite interesting, but in my case, each of those
parties will be in different locations, signing at different times, and we'd
like our system to only transmit the new signature when it takes place and
not the entire data wrapped in a signature.

I'd like to be able to send the DETACHED ds:Signature elements only and thus
update the other party's copies to include the new signature so that the
next time they review their document, the system will show them the newly
arrived digital signature.

Is there a good example of creating a DETACHED signature in the
distribution?

Thanks,
David
