 A name component matcher, enclosed in ``<`` and ``>``, specifies the pattern of a name component. The
 component pattern is expressed with the `Perl Regular Expression Syntax

 For example, ``<ab*c>`` matches the 1st, 3rd, and 4th components of ``/ac/dc/abc/abbc``, but does
 not match the 2nd component. A special case is that ``<>`` denotes a wildcard matcher that can match
 **ANY** name component.
