Regarding when Tag No.43 SequenceReset message set "Y" and handling of Tag No.122

Send message:
When sending amessage with Tag 43=Y do we have to set Tag 122?
If we must set and there is no original message does Tag 122 and Tag 52 have to be a same setting?

Receive message:
Tag 43=Y on SequenceReset message and there is no tag 122, how it supposed act?
Is it has to send Reject message and not accept this SequenceReset?

Best Regards

Following the spec for FIX 4.3/4.2 answers would be:

Yes
Yes
Send Reject( session-level) and increment MsgSeqNum.
Yes
In case I’m interpreting spec incorrectly… I believe someone will clarify this.
