To my understanding they do. * normally equates to zero of more. But should
we allow users to specify their own wildCard or should we prespecify it?
Will we allow ? in a?b* and will this mean that a is optional or that a
single charcacter may occur between a and b? My personal preference is that
we adopt conventions of an existing language (e.g. Perl as used by W3C) for
wildCard specification.
