I think the regular expressions are well-defined over the whole of Unicode,
but of course other specifications restrict the use of C0 in XML. XML 1.0
allows only TAB, CR, and NL, while XML 1.1 allows all of C0 except NUL. It
looks fairly clear to me that those C0 characters that you can actually get
into the system will match \p{IsBasicLatin} - for the others, the question
is academic.
My interpretation.
