Hi Jen,

Thanks for asking -- we struggled with this internally as the wording in the DLF Aquifer guidelines is a bit confusing.

Here's what our internal policy is (and we think it is in sync with DLF Aquifer).

If you are working in an environment or on a project where you are routinely constructing your name subject headings (subdivisions, etc. using the SCM and LCSH), then the subject element should have an attribute authority=lcsh.

Additionally, if the name element within the subject wrapper is in the naf, then the name element should have the attribute authority=naf.
