Just to make the picture a bit darker, I've realized that RFC 2616 for 
HTTP 1.1 is relevant.

The good news: RFC 2616 section 3.7.1 says that, if text/* types are 
sent across HTTP, the CRLF requirement is relaxed and bare CRs and LFs 
are allowed. Good--that's what we wanted to do, anyway.

The bad news: The same section says that if a text/* type is sent across 
HTTP with no charset parameter, it defaults to ISO-8859-1. This is nasty 
stuff, which is in part probably why application/xhtml+xml was chosen 
over text/xhtml+xml, the latter of which would *always* require a 
charset=utf-8 parameter.

This is really heartbreaking. The same concerns appear: are we really 
going to build our future on ISO-8859-1 defaults? Soon no one is going 
to be shipping ISO-8859-1 text across the wire---and of what use will be 
the RFC 2616 default?

Whatever we choose here, I'm sure that Firefox and IE will implement it
