That would be my next question: Although I might have an HTML file encoded
in iso-8859-1, the parser has to interpret following the markup AND using
the Unicode repertoire (CCS).
Does this flexibility is taken into consideration anywhere into Unicode?

Since there is more than one encoding for Unicode CCS, the encoding used has
to be declared. I thought the idea behind Unicode was to be unambiguous. I
see an unambiguous CCS, but not for CEF or CES.
And this is going back to my first question:
If a protocol or format allow different CEF and CES (not only UTFs) but
provide a way to access the whole Unicode CCS and agents have to interpret
it following the Unicode CCS, isn't this compliant (in a way. The "CCS"
way.) with Unicode?
