Existing Wording: Note: All URLs (and ids that form part of the URL) defined by this specification are case sensitive.

Proposed Wording: Note: All URLs (and ids that form part of the URL) defined by this specification are case sensitive. Servers can implement URLs either as case sensitive or insensitive

Comment:

Case insensitive URLs provide more permissive support for requests, and are inline with the W3C guidelines that the implementation of URL paths is left up to the server
