All Implemented Interfaces:

public class AttributeTypeDescriptionSyntaxChecker
extends AbstractSyntaxChecker

A SyntaxChecker which verifies that a value follows the attribute type descripton syntax according to RFC 4512, par 4.2.2:

 AttributeTypeDescription = LPAREN WSP
     numericoid                    ; object identifier
     [ SP "NAME" SP qdescrs ]      ; short names (descriptors)
     [ SP "DESC" SP qdstring ]     ; description
     [ SP "OBSOLETE" ]             ; not active
     [ SP "SUP" SP oid ]           ; supertype
     [ SP "EQUALITY" SP oid ]      ; equality matching rule
     [ SP "ORDERING" SP oid ]      ; ordering matching rule
     [ SP "SUBSTR" SP oid ]        ; substrings matching rule
     [ SP "SYNTAX" SP noidlen ]    ; value syntax
     [ SP "SINGLE-VALUE" ]         ; single-value
     [ SP "COLLECTIVE" ]           ; collective
     [ SP "NO-USER-MODIFICATION" ] ; not user modifiable
     [ SP "USAGE" SP usage ]       ; usage
     extensions WSP RPAREN         ; extensions
 
 usage = "userApplications"     /  ; user
         "directoryOperation"   /  ; directory operational
         "distributedOperation" /  ; DSA-shared operational
         "dSAOperation"            ; DSA-specific operational     
 
 extensions = *( SP xstring SP qdstrings )
 xstring = "X" HYPHEN 1*( ALPHA / HYPHEN / USCORE ) 
 
 Each attribute type description must contain at least one of the SUP
 or SYNTAX fields. 
 
 COLLECTIVE requires usage userApplications.
 
 NO-USER-MODIFICATION requires an operational usage.
