One convention Web 7.0 is looking at adopting is:
1.
A DID without a fragment is an Identity DID
2.
A DID with a fragment is a Locator DID
3.
A DID with an empty-string fragment forces a DID to be a Locator DID
This makes DID typing concrete/structural/robust. Check the above link for where Identity vs. Locator DIDs are used in DID Docs, VCs, and DIDComm Messages (in Web 7.0).
