If an ISO 9660 bridge disc contains Mode 2 Form 1 sectors, then the CD-ROM XA
extensions for ISO 9660 must be used. Further the rules of section 6.11.4 apply.
For CD-R and CD-RW, replace all sections 6.10.3 till 6.10.3.3

6.10.3 Multisession and Mixed Mode
For CD-R and CD-RW, the multisession and bridge disc rules of 6.11 apply with the
following additions:
If random write mode is used, the media may be formatted with zero or one audio
sessions followed by exactly one writable data session containing one track. Other
session configurations are possible but not described here.
When recorded in Random Access mode, a duplicate Volume Recognition Sequence
should be recorded beginning at sector N - 16.
CD multisession discs may also contain audio sessions. The UDF Bridge format allows
CD enhanced discs to be created, see an example in 6.11.5.
