Method and apparatus in mark-up language documents for providing mark-up language hidden attributes

摘要

A system and method for providing at least one hidden markup attribute to convey additional information to target recipients. At least one hidden markup attribute is included in a communication from a server. When a browser at a client/user location receives the communication with the at least one hidden markup attribute, the browser will be able to decode the hidden markup attribute portion of the markup only if it has a correct render key. The render key may be predefined and exchanged between the server and the client. Alternatively, the render key may be communicated to the client with the hidden markup attribute communication. The latter scenario is useful when a server must dynamically calculate the render key based upon the client's capabilities (e.g., discovered during the establishment of communication between the entities). A server may alternatively have a generic default render key for all users.
