[ML] In my opinion this case is considered among the unsupported 
fieldSet values producing a Bad Request response code as stated in 
section 5.

[ML] Not all the responses. Just the responses to search queries which 
are those returning an array of results.

In general, in those responses, the payload due to the metadata 
information is considerably lower than the payload due to the array of 
results.

It wouldn't make sense to provide the subsetting_metadata object as part 
of a lookup response just because, in this case, the sizes of metadata 
and relevant information would be comparable.


Best,

Mario
