Yes I am referring to thid id.

To be honest  your response confused me even more. I understood that this id
"MUST NOT be the URL for the status list"  and that the URL for the
revocation list in this example is "
https://example.com/credentials/status/3". 

Best,
Nikos

I believe you're referring to this value:

https://dmv.example.gov/credentials/status/3#94567

The purpose of the `id` field is to uniquely identify the status of a
specific VC. The URL can really be any identifier that is unique to the
specific status of the specific credential.

The example uses the pattern of using the base URL for revocation list
bitstring and then a fragment identifier for the position of the status bit
in the bitstring.

Base URL for revocation list bitstring is:

https://dmv.example.gov/credentials/status/3

Fragment identifier for the position of the status bit in the bitstring is:

#94567

Keep in mind that it's strongly suggested that folks move on to Status List
2021, as it is a more general mechanism (that could cover revocation as well
as suspension or a variety of other statuses):

https://w3c-ccg.github.io/vc-status-list-2021/

Did that answer your question, Nikos?
