Name Forms can be specified with existing schema components and do not require additional code for its implementation.

The formal specification for attribute types is provided in RFC 4512, section as follows:
NameFormDescription = "(" wsp
numericoid                  ; object identifier
[ sp "NAME" sp qdescrs ]    ; short name descriptor
[ sp "DESC" sp qdstring ]   ; description
[ sp "OBSOLETE" ]           ; not active
sp "OC" sp oid              ; structural object class
sp "MUST" SP oids           ; attribute types
[ sp "MAY" sp oids ]        ; attribute types
extensions wsp ")"          ; extensions followed by a white space and ")"
The following extensions are specific to the PingDirectory Server and are not defined in RFC 4512:
extensions = / 
"X-ORIGIN" /             ; Specifies where the attribute type is defined
"X-SCHEMA-FILE" /        ; Specifies which schema file contains the definition
"X-READ-ONLY"            ; True or False. Specifies if the file that contains 
                         ;   the schema element is marked as read-only in
                         ;   the server configuration.
