Understood.  I'll reach out probably on this list if I run into
major issues.

Thanks, I'll take a look at that.  I'm expecting that the guide is
going to suggest that one should never do what the libxml2 developers did,
but it's still worth my time to review the guide.

Based on how upstream handled the change, I get the feeling that the
"xmlregexp" interface was either little-used or long-deprecated.  I'm
at least a little hopeful that nothing we package was using the interface,
but I won't know until I'm able to start dependent rebuilds.

Thanks,

Tim
