TX_PROP_DENIED

If your client receives a property request that it does not wish to answer, it can openly refuse to answer the request by sending a TX_PROP_DENIED message to the requesting client. This tells the requesting client that you received the query but are unwilling to answer it.

The format for a TX_PROP_DENIED message is:

TX_PROP_DENIED tag address property

where

tag	is a unique label for this message;
address	is the address of the requesting client; and
property	is an envelop whose data field names the property that was queried.

Sending this message will cause the other client to receive an RX_PROP_DENIED message.
