I think we should refrain from claiming that W3C (or some other
organization) recommends something unless we _know_ it does.
I have not seen any such recommendation. You could construe the _default_ as
a recommendation: XML documents are assumed to be UTF-8 or UTF-16 encoded,
unless specified otherwise.
Then there's the practical point that if you use some other encoding, you
should declare it in the XML declaration, which throws IE 6 into Quirks
mode. This has nothing to do with W3C recommendations, though. Besides, you
can specify the encoding in HTTP headers, unless the server administration
prevents that.
There's also the practical point that UTF-16 is a poor choice for web pages,
due to poor support in browsers and search engines.
