Remarks
The RTblIParameterDef table stores parameter definitions associated with MethodDef objects.
The primary key for this table is formed from the IntID, Z_BranchID_Z, and Z_VS_Z columns.
Z_BranchID_Z, Z_VS_Z, and Z_VE_Z are included to provide future support for versioning repository API definitions. At this time, there is only one version of ParameterDef.
