This is more or less to confirm my deeper understanding of IRI and how it all works.
From the docs and the code what I see is, that attachToTangle outsources the PoW to a node. It is broadcastTransactions what sends a "complete" transaction (including the Pow) to the network.
If this is correct, I assume, that a wallet which does PoW itself, never needs to call the attachToTangle API.
Is this all correct?
