After some more investigation I've discovered that XQuery was updated
in Mac OS X 10.5.8 as part of a security vulnerability in the PCRE
library which it includes.
http://support.apple.com/kb/HT3757 (scroll to bottom of page)
Which also explains why all XQuery functions using regular expressions
are also broken. Digging into the PCRE portion of the XQuery code
reveals the following PCRE error string after trying to compile a
regular expression:
"this version of PCRE is not compiled with PCRE_UTF8 support"

Did someone forget to turn on a compile flag?
