> Currently, ExtractText always adds an attribute for the 0th Capturing Group,
> which is the entire text that matched the Regular Expression. This can be a
> very lengthy value and is often not needed. We should add a property (with a
> default value of 'true' for backward compatibility purposes) that allows the
> user to prevent capturing that group.
