-`-incrementalrelayfee`). Policy may include restrictions on the transaction itself, the transaction
+rules are local to the node and configurable, see "Node relay options" when running `-help`.
+Policy may include restrictions on the transaction itself, the transaction
 in relation to the current chain tip, and the transaction in relation to the node's mempool
 contents. Policy is *not* applied to transactions in blocks.
