The D
disclosure type is new for submitMulti
?
I might be mistaken, but I don’t remember we had this earlier. I remember S
for Signatory, O
for observer, W
for Witness.
Without submitMulti
we have this kind of disclosure, without the D
for Alice in contract T

The W
disclosure type is not specific to submitMulti
. The documentation has a brief summary:
The party sees the contract because they have been divulged the contract, e.g., because they witnessed an exercise that resulted in a fetch
of this contract.
With a tiny modification to the example from Can I fetch a contract visible to another party with submitMulti? - #4, we can reproduce the same disclosure: Bob can access the fetch choice directly since the contract is visible to him. Alice is a signatory on TFetch
so she will witness the exercise and thereby also witness the fetch of the contract.
