Beyond non-useful things (like silly EBCDIC linefeeds), there is unfortunately one nice feature that XML 1.1 allows: ability to use character entities for Unicode/ASCII control characters other than LF/CR/Tab. Except that you still can not include nulls, even using character references.

So this is hardly enough to make one use 1.1, unless there is specific need to contain these characters.
