 * Checks a value against a directive type definition.

 * a token value. This function extracts the token portion after the directive
 * prefix and validates it against the token type.
 *
 * @param value - The string value to check
 * @param type - The directive type definition containing directive patterns and token type
 * @param defs - The type definitions registry for resolving nested types
 * @param ref - Optional reference URL for the unmatched result
 * @param cache - Whether to use cached results (defaults to `true`)
 * @returns The validation result
