Summary: Document is clear, well-written, and short. Thank you!

Major issues: None

Minor issues: After reading the document, I was somewhat
confused as to the definition of fieldSet query parameter.
I think adding a few sentences to Section 2 explaining that
a field set is a string that the server generates which maps
to a set of fields only known to the server would help.

[ML] It seems to me that both the concepts are already conveyed in the document. Maybe they are not adequately clarified.

The sentence "... whose value is a string identifying a server-defined set of supported fields.." means that a field set name and the related list of fields are defined by the server.

With regards to the assumption that a field set is known only by the server, this is not generally true.

Both the field set names and the related list of fields might (hopefully should) be shared by as many servers as possible to facilitate interoperability as described in section 4.

Moreover, the field sets together with other server features are expected to be described  in out-of-band documents like the RDAP profile.

Finally, as described in section 2.1, the subsetting_metadata element could provide an in-band information about the supported field sets that is more reactive to server updates than out-of-band contents.

Do you think that the concepts above should be furtherly clarified ?

Additionally, specifying that the string can't be empty and
which characters are allowed might help avoid interop
issues down the road.

Nits/editorial comments: None

[ML] Agreed.

But rather than updating section 2, I think that it would be better to change the section 5 as in the following:

OLD

Each request including an unsupported field set SHOULD produce an
   HTTP 400 (Bad Request) response code.

NEW

Each request including either an empty or an unsupported "fieldSet" value 
SHOULD produce an
   HTTP 400 (Bad Request) response code.

Is it okay with you?


Best,

Mario
