FIXML just describes business content. It does not define any kind of session layer, and it is expected that FIXML users will use some type of protocol or middleware that provides for reliable, ordered message delivery.
A heartbeat doesn't have any place in FIXML. Determining if the other side is still alive is a session-level task left to the underlying protocol or middleware, which can inform the business application via some out-of-band means.
If FIXML is transported inside Tag=Value FIX, then the FIX Engine will use heartbeats.
FIXML does not have a Logon message, but that has nothing to do with start of day. I believe the message you need is Trading Session Status.
