If the OPTIONAL part is not present the pointer will be NULL
If it is present, it will allocate a structure only if there are members
in the SEQUENCE OF. If the SEQUENCE OF turns out to have 0 elements in
it it will be the same as if the SEQUENCE OF was not encoded.
You cannot distinguish between these two cases with posy/pepsy. Either
the element is there and has 1 or more components or it is treated as abesnt.
