Did xpath_table get dropped.

I don't see anything to that effect in the release notes I've looked at.

I built 9.1.2 from source with these options.

CONFIGURE = '--with-libraries=/lib:/lib64:/lib/x86_64-linux-gnu'
'--with-python' '--with-openssl' '--with-ossp-uuid' '--with-libxml'
'--with-libxslt'

\df xpath*
