Apparatus and methods are disclosed, such as those involving a memory device. Each XML schema definition is compiled once into the AAE format, rather than being compiled each time an XML document is validated, and thus significant time is saved. A metal connection ring is embedded around the outer periphery of the base and is contacted by the cathode. By using an event to identify media assets to which contextual information is associated, fewer and more relevant media assets may be retrieved and annotated as compared to conventional techniques. The FET-like structure is formed with thinner oxide than the gate oxide of the FET, has a gate structure connected with the gate of the FET, and may be shorted out by the first metal layer.
