Corrected Text
--------------
   ospfTrapCompliance MODULE-COMPLIANCE
        STATUS       obsolete
        DESCRIPTION
           "The compliance statement."
        MODULE       -- this module
        GROUP       ospfTrapControlGroup
        DESCRIPTION
           "This group is optional but recommended for all
           OSPF systems."
        ::= { ospfTrapCompliances 1 }

Notes
-----
ospfTrapControlGroup is listed both in the MANDATORY-GROUPS clause and in a GROUP clause. Per RFC 2580, Conformance Statements for SMIv2 (brackets added to indicate pertinent rule):

"5.4.2.  Mapping of the GROUP clause

   The GROUP clause, which need not be present, is repeatedly used to
   name each object and notification group which is conditionally
   mandatory for compliance to the MIB module.  The GROUP clause can
   also be used to name unconditionally optional groups.  [A group named
   in a GROUP clause must be absent from the correspondent MANDATORY-
   GROUPS clause.]"

It is listed in both clauses in RFC 1850 as well (which RFC 4750 obsoletes). It is STATUS current in RFC 1850 and STATUS obsolete in 4750; however, obsolete or not, it is not legal according to SMI rules.
