   I agree with Bjoern.

'At least until ....' phrase can be interpreted to mean the following, 
too (which is similar to what Tex wrote in his first message in this 
thread) A document can be in two encodings, the first of which is ASCII 
and used until 'meta charset' declaration appears. After declaring 
charset to be UTF-16LE(EBCDIC, or whatever), it can be in UTF-16LE. This 
is rather 'crazy', but it seems like that's a possible scenario. Well, 
I'm being lazy here... I should go and find out in what context the 
above paragraph was written.

FYI, Mozilla does what XML 1.x Appendix F recommends (although it's 
non-normative), on which CSS 2.1 recommendation is more or less based 
(with some changes).
