          According to the PDF specification, OpenType fonts can only be
          embedded beginning with PDF version 1.6; PDF/A-1 requires PDF
          1.4. This would mean that PDF files with embedded OpenType
          fonts cannot be converted to PDF/A. Despite this, the
          conversion seems to have worked.

It is correct that OpenType fonts cannot be embedded in PDF/A files. 
However, OpenType fonts are often converted to another type (TrueType or 
Type1) when they are embedded, so creating a PDF/A file should usually 
not be a problem. If Acrobat 8 recognized the file that you converted to 
PDF/A as being compliant, then a conversion of the font type probably 
took place. You can verify the font type of embedded fonts using the 
Preflight verification report (Check box: “Show detailed information 
about document”, and then look under “Fonts”).


see
http://en.wikipedia.org/wiki/PDF/A

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.
