| /** |
| * A matchingRule definition. MatchingRules associate a comparator and a |
| * normalizer, forming the basic tools necessary to assert actions against |
| * attribute values. MatchingRules are associated with a specific Syntax for the |
| * purpose of resolving a normalized form and for comparisons. |
| * <p> |
| * According to ldapbis [MODELS]: |
| * </p> |
| * |
| * <pre> |
| * 4.1.3. Matching Rules |
| * |
| * Matching rules are used by servers to compare attribute values against |
| * assertion values when performing Search and Compare operations. They |
| * are also used to identify the value to be added or deleted when |
| * modifying entries, and are used when comparing a purported |
| * distinguished name with the name of an entry. |
| * |
| * A matching rule specifies the syntax of the assertion value. |
| * |
| * Each matching rule is identified by an object identifier (OID) and, |
| * optionally, one or more short names (descriptors). |
| * |
| * Matching rule definitions are written according to the ABNF: |
| * |
| * MatchingRuleDescription = LPAREN WSP |
| * numericoid ; object identifier |
| * [ SP "NAME" SP qdescrs ] ; short names (descriptors) |
| * [ SP "DESC" SP qdstring ] ; description |
| * [ SP "OBSOLETE" ] ; not active |
| * SP "SYNTAX" SP numericoid ; assertion syntax |
| * extensions WSP RPAREN ; extensions |
| * |
| * where: |
| * [numericoid] is object identifier assigned to this matching rule; |
| * NAME [qdescrs] are short names (descriptors) identifying this |
| * matching rule; |
| * DESC [qdstring] is a short descriptive string; |
| * OBSOLETE indicates this matching rule is not active; |
| * SYNTAX identifies the assertion syntax by object identifier; and |
| * [extensions] describe extensions. |
