/**
* The definition of a DIT content rule in the schema.
* <A HREF="http://www.ietf.org/rfc/rfc2252.txt"
* TARGET="_blank">RFC 2252, Lightweight Directory Access Protocol (v3):
* DIT Content Rule Description</A> covers the types of information
* to specify when defining a DIT content rule. According to the RFC,
* the description of a DIT content rule can include the following:
* <P>
*
* <UL>
* <LI>an OID identifying the attribute type
* <LI>a name identifying the attribute type
* <LI>a description of the attribute type
* <LI>the name of the parent attribute type
* <LI>the syntax used by the attribute (for example,
* <CODE>cis</CODE> or <CODE>int</CODE>)
* <LI>an indication of whether the attribute type is single-valued
* or multi-valued
* </UL>
* <P>
*
* When you construct an <CODE>LDAPDITContentRuleSchema</CODE> object, you can
* specify these types of information as arguments to the constructor or
* in the AttributeTypeDescription format specified in RFC 2252.
* When an LDAP client searches an LDAP server for the schema, the server
* returns schema information as an object with attribute values in this
* format.
* <P>
*
* There are a number of additional optional description fields which
* are not explicitly accessible through LDAPDITContentRuleSchema, but which
* can be managed with setQualifier, getQualifier, and getQualifierNames:
* <P>
*
* <UL>
* <LI>OBSOLETE
* </UL>
* <P>
*
* To get the name, OID, and description of this DIT content rule
* , use the <CODE>getName</CODE>, <CODE>getOID</CODE>, and
* <CODE>getDescription</CODE> methods inherited from the abstract class
* <CODE>LDAPSchemaElement</CODE>. Optional and custom qualifiers are
* accessed with <CODE>getQualifier</CODE> and <CODE>getQualifierNames</CODE>
* from <CODE>LDAPSchemaElement</CODE>.
* <P>
*
* To add or remove this attribute type definition from the
* schema, use the <CODE>add</CODE> and <CODE>remove</CODE>
* methods, which this class inherits from the <CODE>LDAPSchemaElement</CODE>
* abstract class.
* <P>
* RFC 2252 defines DITContentRuleDescription as follows:
* <P>
* <PRE>
* DITContentRuleDescription = "("
* numericoid ; Structural ObjectClass identifier
* [ "NAME" qdescrs ]
* [ "DESC" qdstring ]
* [ "OBSOLETE" ]
* [ "AUX" oids ] ; Auxiliary ObjectClasses
* [ "MUST" oids ] ; AttributeType identifiers
* [ "MAY" oids ] ; AttributeType identifiers
* [ "NOT" oids ] ; AttributeType identifiers
* ")"
* </PRE>
*
* @version 1.0
* @see netscape.ldap.LDAPSchemaElement
