RE: [legalxml-enotary] Evaluation of consultant deliverable: symmetric key

[John Messing <jmessing@law-on-line.com>]

Arshad:

With regard to the use of XML DSIG for symmetric key signings, I must
admit I was thrown by seeing in the schema the existence of the
X509DataType, which I now see has min occurrences of "0". Athough I do
recall some experiments I once performed on adapting DSIG to symmetric
signing in connection with the development of the LegalXML
eCourtDocument 1.1. standard, along with Rolly Chambers and Mo
Abdulaziz, I do not recall finding guidance at the time for such usage
of DSIG. I think understand and appreciate using a URI in connection
with the key retrieval, but I was wondering if you developed this method
on your own, or if you found antecedents, and if the latter, you would
be willing to share them with the group.

Thank you.
