• [x] The DID Method specification defines the Create, Read, Update, and Deactivate DID Method Operations.
• [x] The DID Method specification contains a Security Considerations section.
• [x] The DID Method specification contains a Privacy Considerations section.
• [x] The JSON file I am submitting has passed all automated validation tests below.
• [x] The JSON file contains a contactEmail address [OPTIONAL].
• [x] The JSON file contains a verifiableDataRegistry entry [OPTIONAL].

In method-specific-identifier section I'd like a little more explanation about method-specific-id. Of course, we can know SM3 format by reading SM3 specification, but I'd like some information on length, etc.

Example

method-specific-id = <hexdigit>{64}
hexdigit = [0-9A-F]

I have modified the explanation about method-specific-id in https://github.com/617640999/ctid-did-register/commit/e44aa3d50cf199726122edadd7431d0fc918c1fb, please check again whether it meets the registration requirements. Thanks!

Is it possible to clearly dissociate the security aspects from the privacy considerations in the last section? Please, try to clearly point out in the security part as present in the document at https://w3c.github.io/did-core/#security-requirements

Thanks for your review, I have updated my registration request to split security and privacy considerations into two points. Please help review again. link to this registration
