That seems quite reasonable. The ISO9660 standard leaves
enough blocks early on undefined that you can build a
CD that is both a legal ISO9660 filesystem and a legal
OpenVMS (ODS-2) filesystem.

If you try hard enough, you can build a hybrid system where
the ODS-2 and ISO9660 sides have different trees but share
the same data (useful for stream-LF and binary files).

I presume RSTS is ODS-1, which IIRC is ODS-2 but without
a few of the bells and whistles so the structure is 
quite close to ODS-2. I would expect that you could
interleave ODS-1 and ISO9660 fairly easily.
