Nobody seems to be complaining about having to tokenize attribute values
that contain Unicode values. In what way is this any easier than the
tokenization of Unicode PCDATA? (Or is this just being overlooked at present?)

We have to bite the Unicode tokenization issue at some stage. The mixed
content thing seems to be confusing the issue. Are we agreed that counting
of tokenized Unicode characters within individual pieces of PCDATA is no
more difficult thatn counting them in attribute values? If so, would it help
to apply the rules used for white space recognition in attribute values to
counting of white space within mixed content?
