Hi all,

Here my WGLCv2 comments on draft-ietf-core-href-18. Because it is long and (to me) complex, I haven’t read the entire text from A to Z.
Overall, the practical CRI usage looks clear and easy enough, with some good examples given.

There are some items to be fixed or looked at I think before the document can proceed:

• Section 8.2.2 is missing some precedence rules like 8.2.1 has. For example if Proxy-Scheme and Proxy-Scheme-Number options would be used in the same CoAP message, which takes precedence? (Assume it’s Proxy-Scheme)
https://github.com/core-wg/href/issues/104 

• Unclear sentence in abstract with “describes cooperates” - https://github.com/core-wg/href/issues/102

• Section 8.2.2 has a “TO DO” item - https://github.com/core-wg/href/issues/103

• Section 11.1.2 has for the "Reference" field: "a reference to a document, if available, or the registrant" -> maybe better to clarify to "a reference to a document requesting the registration, if available, or the registrant"
  Is this intended? The initial registry contents only have "RFC-XXXX" as the reference which is the document requesting the registration, not the document describing the scheme semantics.
  If the Designated Expert at own initiative requests the registration per 11.1.1 , what would the "Reference" field contain then? The name of the expert or the RFC number that defines the new scheme?
https://github.com/core-wg/href/issues/105

regards,
Esko
