The problem with that subset (at least as currently written) is it would not support unicode.

I support this, just wanted to point out some material we wrote up for regex in CybOX 2.1: http://cyboxproject.github.io/documentation/regex-support/. The intent was to identify the subset of PCRE that’s compatible across the most common programming languages and frameworks. It or something like it could be included as non-normative text or best practices to encourage people to use more compatible regexes.
(Please ignore the note at the bottom about alternative syntaxes, we shouldn’t do that).

Seconded - we need to move forward.

Hello,
I would like resolve the issue of regex for patterning.
Unless anyone voices any objections, we will use PCRE as the regex grammar for the MATCHES operator.
Thanks.
