Major Changes No longer a template; now simply an extension (using Supported/Require). Arbitrary nesting of lists is allowed. Lists may contain individual resources and lists at the same level. Meta-information moved into own XML body part. 12-page example added.

Open Issue: Filters RFC 3265 allows bodies for applying filters to the subscription. The interaction with lists is tricky. Does the body apply to the top-level list, the nodes, or both? Note that filter syntax may vary depending on the answer. Could make filters a provisioned part of the list, but doing so is not a complete solution. Similar issue arises with Event header parameters.
5
Help: I Am Not An XML Guy Read through as much of the W3C spec as I could take in one sitting, but not certain my usage is 100% correct. Need an XML expert to look over usage of XML in draft, and to provide feedback.
6
Example 1: Metainformation
7
Example 2: Downstream Forking
8
TBD Some editorial cleanup to separate specific example of “pass through” of subscriptions from normative sections.
9
What Now? Need discussion on the list about handling of filters. Generally, needs more eyeballs. (Shouldn’t take long: only 16 pages of spec, 12 pages of example). Other than that, should be ready for last call.
