Re: [CDNi] I-D Action: draft-ietf-cdni-uri-signing-22.txt

To save a click, here's the text:

The URI Signing Package will be found by parsing any path-style parameters and
form-style parameters looking for a key name matching the URI Signing
Package Attribute.
Both parameter styles MUST be supported to allow flexibility of operation.
The first matching parameter SHOULD be taken to provide the signed
JWT, though providing
more than one matching key is undefined behavior. Path-style
parameters generated in the
form indicated by Section 3.2.7 of [RFC6570] MUST be supported.
Form-style parameters generated in the form indicated by Section 3.2.8
of [RFC6570]
MUST be supported.

The last two sentences are what I'm proposing we add. This was the
simplest variation I could come up with that doesn't add a whole bunch
of construction rules to this document, but provides at least one
clear MUST-accept implementation for each style that allows a dCDN to
be certain that it knows how to find the URIs.
