They are, but not in match expressions. (However, libxslt
*does* allow those in match expressions as well. Xalan and
Saxon both choke on them, as the spec says they should.)

Well, I can't reproduce your problem with:

pavel@debian:~/dev/xslt$ xsltproc -V
Using libxml 20629, libxslt 10121 and libexslt 813
xsltproc was compiled against libxml 20628, libxslt 10121
and libexslt 813
libxslt 10121 was compiled against libxml 20628
libexslt 813 was compiled against libxml 20628

You didn't give enough context to be sure, but I'd bet this
has been fixed between 2.6.21 and 2.6.27. Note that your
xsltproc uses 2.6.21. I know for sure there was an obscure
known bug with xpath.c in libxml 2.6.26 that was fixed
since then, so I think updating your packages should solve
your immediate problem.
