I think your reference to the CD-ROM XA spec as "the Yellow book ISO 9660
extension" may confuse people into thinking XA is the one and only Yellow Book
and ISO 9660 extension. While CD-ROM XA is an extension to both the Yellow
Book and the ISO 9660 spec., there are many others. XA is simply one Yellow
Book and ISO 9660 extension.
As long as picking nits, the term Yellow Book is really obsolete. The Yellow
Book was Philips's and Sony's original proprietary proposal for a CD-ROM
format. It is superseded by the newer international CD-ROM standard, ISO/IEC
10149. Yellow Book is sort of like the High Sierra directory format: the
original draft proposal by the industry leaders. ISO/IEC 10149 is like ISO
9660; it's the final, open, international standard. However, ISO/IEC 10149 is
much closer to the draft Yellow Book standard than ISO 9660 is to the draft
High Sierra standard.
