No, I didn't mean positionally within the zone file. Record order is
mostly irrelevant in zone files (but the SOA record must be first).
The "bottom" of a zone is any delegation point to a subzone. "www.my"
is below a delegation of "my". The exception is glue records, which
are address records that belong to the subzone but are present to
support the delegation itself.
