Re: [TLS] Document Action: 'TLS Elliptic Curve Cipher Suites with SHA-256/384 and AES Galois Counter Mode' to Informational RFC

[Russ Housley <[e-mail]>]

http://www.ietf.org/ietf/IPR/certicom-ipr-rfc-3446.pdf  seem to cover 
TLS and ECC.  However, I agree that Certicom should be asked to 
update the IPR statement to cover TLS 1.2 as well as the recent 
Internet-Drafts.
