I am writing to urge the IETF to reject the TLS Authorization Extensions, unless the Extensions can be implemented fully (including all Authorizations and access control methods) without royalty or other encumbrance. Freely implementable IETF standards are vital to the openness of the internet. Fundamental protocols like TLS must not be encumbered by patent restrictions, which make it impossible for free software to fully implement them. Thus, I urge you not to approve TLS Authorization Extensions as any form of standard. Thank you for your consideration.
