Match if the element is in a match list. match is used only with _xWILD, and succeeds only if one of the list names matches a node. match and fail basically convert _xWILD from a wildcard to a restricted match or fail on a list of names.
match can only be used with _xWILD rule elements. matches is an alternate form for match.
