/*-
 *  Reference RFC 6020.
 *
 *  The pattern Statement
 *
 *  The "pattern" statement, which is an optional sub-statement to the
 *  "type" statement, takes as an argument a regular expression string.
 *  It is used to restrict the built-in type "string", or types derived
 *  from "string", to values that match the pattern.
 *
 *  If the type has multiple "pattern" statements, the expressions are
 *  ANDed together, i.e., all such expressions have to match.
 *
 *  If a pattern restriction is applied to an already pattern-restricted
 *  type, values must match all patterns in the base type, in addition to
 *  the new patterns.
 *  The pattern's sub-statements
