Supported?

It's been around for several years, beginning with the first version of Oracle's App server. I guess it's supported.

It seems to be bug free, and is based on std regular expression definitions. The source is included as well.

Just when I think I'm cought up on the Oracle-installed PL/SQL packages...

Seeing as OWA_PATTERN isn't in the docs (not on tahiti, anyway), is it supported???
