Swapping your sentences around: yes, the whole idea of +xml is that you know you can use a generic XML parser.

Something that might or might not be xml, therefore should not use +xml.

An XML parser must understand UTF-8 and UTF-16 and may understand other encodings. I gather that the Efficient XML folks will declare a new encoding, and parsers which don't know it will not parse it. Same is if I said the encoding was

encoding="i-bet-you-never-heard-of-this-one"
