>From ZigBe_Alliance-zcl-urn-application-FINAL-03Aug16.txt: I see that "Declaration of syntactic structure" says: URNs assigned by the ZigBee Alliance will have the following structure based on the organizational structure of the resources specified in the ZigBee Alliance specifications: urn:zcl:<NSS> where the syntax of "<NSS>" is specified in Section 2.2 of the URN Syntax requirements [RFC2141]. whereas "Rules for Lexical Equivalence" says: The "<NSS>" is case-sensitive. Only lower case letters are considered valid. These are not consistent, since <NSS> allows upper-case letters (both as part of %-escapes and in their own right). If you really mean to forbid upper-case letters, you need to state that in "syntactic structure". E.g., urn:zcl:<NSS> where the syntax of "<NSS>" is specified in Section 2.2 of the URN Syntax requirements [RFC2141], except that it may not contain upper-case letters. Also, the "urn" and namespace parts are case-insensitive (RFC 2141, sections 2 and 2.1), so "equivalence" should be updated to, perhaps The "<NSS>" portion of URNs is compared as a character string.
