3.2.1 Abstract Data Model
This section describes a conceptual model of possible data organization that an implementation maintains to participate in this protocol. The described organization is provided to facilitate the explanation of how the protocol behaves. This document does not mandate that implementations adhere to this model as long as their external behavior is consistent with that described in this document.
accept-unmasked-frame: When set to false, this flag indicates that unmasked frames are to cause the connection to be aborted. When set to true, the server is to accept frames regardless of whether they are masked.
