IMHO, WiMAX and Wireless Networks operators that use TLS based-certificate
have interests in providing alike GSM and UMTS modele for identity hiding.

I CCed Joe Salowey who could have more arguments regarding the certificate
hiding in WLAN and WiMAX using TLS.

Thank you. It is clear for me now. However, sentences will be added to the
Security Considerations, in order for the client to check its
understanding of the server hostname against the server's identity as
presented in the server Certificate message.
