I can argue the other side of the argument for HTML and XML, though..... 
the main thing being that humans who *enter* IDNs in Unicode form 
without the benefit of conformance-enforcing software interfaces will 
just about always get them wrong (due to bizarrities of case, 
compatibility characters and other weirdnesses).

If they enter A-labels by hand, it's pretty certain they've 
cut-and-pasted them.
