All Unicode separator characters are expected to be matched by \s eventually,
while searching in UTF-8 strings (Camel III, p. 168).

Perl 5.6.0 doesn't include U+0085 in \s yet.

This is not an error in the XML 1.0 spec, IMHO. Apparently, U+0085 was
assigned in Unicode 3.0, and XML 1.0 is based on Unicode 2.0.

XML 1.0 could not possibly comply in 1998 with a standard published in 2000.

The difficult question is if any change in Unicode should trigger an
instantaneous XML revision, or not. IBM thinks it should.

Unfortunately, if U+0085 is included as whitespace in the XML spec, it won't be
XML 1.0 anymore.
