Actually, the feature is 100% documented in ISO 32000-1:2008. HOWEVER, the feature involves the use of Digital Signatures/Certificates and so a pair of them is needed. Adobe and others implement this by incorporating the public certificate into their readers, and then use the private cert at creation time.
Since only Adobe has their private certificate, only Adobe products can enable Adobe Reader. Just as only other companies can enable their own readers, and Adobe can not.
