It doesn't. Subsets are allowed.

What about pdf/a and opentype ?

A new part to the standard, ISO 19005, Part-2 (PDF/A-2), is currently being worked on by the Technical Committee. PDF/A-2 will address some of the new features added with versions 1.5, 1.6 and 1.7 of the PDF Reference. PDF/A-2 should be backwards compatible, i.e. all valid PDF/A-1 documents should also be compliant with PDF/A-2. However PDF/A-2 compliant files will not necessarily be PDF/A-1 compliant.


The font type conversion in Acrobat is interesting. Anyhow, I never used PDF/A.
