XML provides an unambiguous default. Is there a practical reason, due
to broken real-world UAs perhaps, not to PASS defaulted UTF-8?

Related issues: (space separated ids)

WG Notes: Right, we're asking content to go ahead and specify the default to give every possible hint to the UAs, and stop them from ever trying to second-guess the default and choose another encoding. JR: Plus if the encoding is not specified in the HTTP Header then that can mean that a non-UTF-8 default could be inferred. So we require explicit definition of the encoding somewhere.
