[M4IF Technotes] Are AL18 and AL19 equivalent to AL09 and AL10 ? which is the equivalent for AL11 ?

[Apoorva Ankad]

Dear Experts,
          I am testing the AAC Decoder. According to the standard, the
PNS bit streams are to be checked in a special manner. It has spectral
conformance test to be done on Sequences AL09, AL10 and temporal
conformance on AL11. But all these sequences are missing. But, the
streams AL18 and AL19 are PNS coded. But, I am not getting to know
whether AL18 and AL19 are equivalent to AL09 and AL10. If that is the
case then, which is the equivalent for AL11 on which I have to perform
the temporal conformance tests ?
Eagerly waiting for your reply's
