True, but look at Blood of Fiends. I've never seen the actual AP #25 but I have seen the citation on the d20PFSRD website. They appear to be the same as the alternate heritages listed in Blood of Fiends which is listed as legal material on the same page that was listed above. Might want to look into it.

The answer to this question and many others can be found on the Additional Resources page: http://paizo.com/pathfinderSociety/about/additionalResources
You may wish to check the PFS FAQ, which is presently http://paizo.com/paizo/faq/v5748nruor1fq but if that URL changes you can find it at the FAQ page, http://paizo.com/paizo/faq which also contains many other useful documents.
And of course there is always the Guide to Pathfinder Society Organized Play, a free download available here: http://paizo.com/products/btpy84k4
Pathfinder Player Companion: Blood of Fiends
Bloodlines: daemon bloodline is not legal for Pathfinder Society; Feats: all feats on pages 24–25 are legal; Heritages: all heritages, and associated traits, on pages 18–23 are legal;
The heritages listed on 18-23 have all the information on them as the SRD, plus a little fluff, and two additional traits.
