I would like some clarification about: ept_map Method

The resulting method definition is specified as follows.

void ept_map(
[in] handle_t hEpMapper,
[in, ptr] UUID* obj,
[in, ptr] twr_p_t map_tower,
[in, out] ept_lookup_handle_t* entry_handle, [in, range(0,500)] unsigned long max_towers, [out] unsigned long* num_towers, [out, ptr, size_is(max_towers), length_is(*num_towers)]
twr_p_t* ITowers,
[out] error_status* status

obj: Optionally specifies an object UUID. A value of NULL indicates that no object UUID is specified.

>From our investigation, it looks like the obj is completely ignored in Windows and this is not documented. The OpenGroup implementation checks if
   it is a valid object id of a registered interface.

Could you please clarify in the docs if it is ignored and if not what is the difference to the OpenGroup implementation or specification.
