ObjectId - Specifies the numeric ID of the object
ObjectName - Specifies the encoded node and leaf of the object

Routine Description:
IsmAreObjectsIdentical determines if two objects are identical or not.
If they are of a different type they are automatically different.
The compare callbacks are all called passing them the information
that if previous callbacks already gave a resolution. If no
compare callback is found valid, a default compare (binary compare) will
be performed.
Arguments:
SrcObjectTypeId - Specifies the first object type ID
SrcObjectName - Specifies the first object name
SrcContent - Specifies the first object content
DestObjectTypeId - Specifies the second object type ID
DestObjectName - Specifies the second object name
DestContent - Specifies the second object content
DifferentDetailsOnly - If the objects are different, tells the caller
that only the details (not the actual content)
were different
Return Value:
TRUE if the objects are identical, FALSE otherwise
