The motd contract uses the XSLT contains() function to determine
whether the motd is displayed for a given path. It does not appear
that the contains() function is intelligent enough to do what you
want. Also, a brief search shows a general lack of support for regular
expressions in XSLT 1.0.

Perhaps the motd could be injected via the Cocoon pipeline, where
regular expressions are supported.
