Obviously, a prefix matches a prefix set literal iff it matches any prefix pattern in the + or <cf/high/. Obviously, a prefix matches a prefix set literal if it matches any prefix pattern in the prefix set literal. There are also two shorthands for prefix patterns: <cf><m>address</m>/<m/len/+</cf> is a shorthand for |
