Your spec isn't generic. The parser you use shouldn't be either. Custom fields, groups and messages are supported out of the box.
Sensitive production data? No problem. Your logs never leave your machine.

This message requests a Heartbeat <35=0> from the opposing application, to verify it is still responsive. The other application responds with a Heartbeat <35=0> echoing back the given TestReqID (112).
TestReqID (112) ensures that the opposite application has generated the Heartbeat as the result of a specific Test Request and not a normal timeout. The opposite application includes the TestReqID in the resulting Heartbeat. Any string can be used as the TestReqID, but uniqueness is preferable for debugging purposes. Timestamps, sequences, or UUIDs are sensible choices.

Fixdev tools are custom-built for FIX; your word processor isn't. Forget about updating the same data in multiple places, and edit message structures without fiddling with another table.
Fixdev ensures yours spec is always left in a valid state. You'll be warned before deleting fields which are in use, and about other issues which would break your spec.
You're in control of who sees your specs: from specific users, to the entire world
