I'd actually contact the APA and ABA and ask. I think breed clubs have to get special permission to reprint the Standards, or else they'd probably be more available than they are. Reason being, if it was all available easily online, no one would buy the book.
I guess think of it this way, if an author gives a website special permission to print part of their book on their page, then only that website has the permission. If you then copied that text and put in on your own website, even if you cited the website you got it from, you still don't have the content owner's permission to have it on your site, and that could be copyright infringement.
So since I have to renew my APA membership and I was emailing the APA anyway to ask when my dues were due, and we had this question of whether the standards can be published, I went ahead and just asked. This was the response from David Adkins, the APA secretary:
"...the material in the Standard of Perfection is copyrighted material and cannot be printed/published in any form without the consent of the APA." He went on to say that the president of the APA, John Monaco, should be contacted to ask about permission.
So unfortunately, without the express permission of the president of the APA, and I would assume also the ABA for their standards, the standards cannot be published
