No, it's not.

I suppose bash could say: See your system regex(3)
implementation documentation for the description of extended
regular expression syntax on your system. That syntax should be
compatible with one version or the other of the POSIX Extended
Regular Expression syntax whose specification for the latest
version as of writing can be found at:
http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html#tag_09_04

regex(3) points to the API (regex.h), how the system documents
the regexps covered by that API is beyond bash knowledge.
