RE: [Uri-review] In WG last call review of URI Schemes rtsp, rtsps and rtspu

I think it is in scope to fix the registration guidelines to clarify the registration process, in areas where registrants often make mistakes.

This is one of them.

== proposed add ==
"In general, a URI or an IRI can be thought of as   consisting of
    <scheme>:<scheme-specific-part>#<fragment>.

However, the registration defines <scheme> and the syntax and semantics of <fragment>  depends only on the media type of the representation accessed. New scheme definitions MUST NOT define syntax or semantics of fragment identifiers; that is, registration specifications should define the syntax of <scheme-specific-part> and its meaning for each <scheme> defined.

I think that is quite explicit already, but a reminder seems to be in
order, I've certainly complained about this in a number of registrations
and encountered a number people, and implementations, that had bizarre
ideas about fragment identifiers being specific to individual schemes.

The general idea would be to say something like URIs are

  <scheme>:<scheme-specific-part>#<fragment>

and schemes can only constrain the first two components. It might be a
good idea to ask people who got this wrong in the past what could be
done to avoid their confusion.
