So, I'm perplexed.

All the browsers I'm familiar with (I haven't installed Chrome yet)
support XML+XSLT via the xml-stylesheet processing instruction.

So they all have case-preserving tokenizers whose performance is
acceptable for the people who serve and read XML+XSLT.

Who then has ruled that a case-preserving tokenizer "imposes an
unacceptable performance penalty", and on the basis of what evidence?
