Yep that means your regex look fine, thanks!

I had a thought: it would be really cool to make a quick PushPull
command line tool that simply wraps ExpressionValidator and examines
the RemoteSpecs directory to validate all the regexes in that file.

I've filed: https://issues.apache.org/jira/browse/OODT-475 

to track my thoughts on the issue.

Cheers,
Chris
