Subject: RE: NHIN Exchange <Subject> question
All, This issue is highly important to the NHIN Exchange. It is currently blocking a state health information exchange from joining the NHIN Exchange, and two vendors (perhaps more) are in a holding pattern depending on the authoritative resolution to this issue. What is the proper path for getting a consensus initial opinion and ultimately an authoritative statement on this (and some closely related) topics? Would it be helpful if I provided revised SAML text intended to replace the existing text?

Here's the ambiguity: Since a SAML assertion can have multiple <Subject>s, the quoted text ambiguous since it is not clearly specifying which <Subject> is being referenced as being required. -----Original Message----- From: Cantor, Scott E.
