The rework is more permissive than what you had suggested initially
(conditioning acceptance of a noncompliant NSR on a preceding BEA).
I had also tried to code the original so that a malformed 2048-byte
interval VRS would not be accepted. But the simplifications do make
the code easier to follow...

Thanks,
