Rem    NAME
Rem      ordimssp.sql - ORDIM Signature Spec.
Rem
Rem    DESCRIPTION
Rem      This is the type specification for ORDImageSignature and specification
Rem      of package ORDImgSig_Pkg
Rem
Rem    NOTES
Rem      Till 10G production this code resided in ordispec.sql, along with the
Rem      type specification of ORDImage.  In 10G, an OID was added
Rem      to ORDImageSignature, and it was moved to separate file so
Rem      that type creation of ORDImageSignature can be called independently
Rem      of type creation of ORDImage.
