## OPERATION: Empty Body with "echoOkUltimateReceiver" header block via an intermediary, relay="true". (Test ST1)

This operation sends a string value in the echoOkUltimateReceiver header block, which is understood only by the ultimate receiver. The target of the header block is the role "next". relay is "true", and mustUnderstand is "false", so the header block is relayed by the intermediary to the ultimate destination (configuration based static routing is used, no routing header entry is present).
