Just a little feedback here, since I have applied all the other
requested changes...

Done now.

Jup, done.

Is that really necessary? They are just random Web users, really....
Where they have specific features, they are mentioned.

Hopefully the scenarios are now in better context and more readable.

They are now right up front and have an introductory paragraph that
should help decide whetehr to read it or not.

Done and done.

I don't think so. 4.3 (now 3.3) bascially says we should use # and not
? in URIs. 4.4 says the retrieved resource should be a valid file.

It just says that a simple change to the URI should get us access to
the parent resource (i.e. the full resource). It means: chopping off
the #-part will lead us to the full resource.

I have re-forumlated it and included transcoding as a necessary by-product.

This section simply states that if we have to make changes to the
extisting infrastructure, i.e. to User Agents, Web proxies and Web
servers, the changes should mainly concern Web servers. Web servers
have to implement the fragement extraction algorithms anyway, so
further code changes should mostly concern server software. Does that
clarify it? If yes, can you propose changed wording that clarifies

I think somebody else has already fixed this.

Have changed the title - should be clearer now.
