                   HTTPMethodList

 </pre>

 <p>
 If duplicates occur in the HTTPMethodSpec they must be eliminated by the permission constructor.

 <p>
 A null or empty string HTTPMethodSpec indicates that the permission applies to all HTTP methods at the resources
 identified by the URL pattern.

 <p>
 If the HTTPMethodSpec contains an HTTPMethodExceptionList (i.e., it begins with an exclaimationPoint), the permission
 pertains to all methods except those occurring in the exception list.
