Not sure if this is what you mean, but according to Graziano's theory, the attention schema is constantly being updated to reflect what is going on in attention. That information is then available for the attentional system where different parts of the brain compete about what to pay attention to. In this theory the attention mechanisms are the processors, and the attention schema is the informational model of what those processors are doing. Changes to the attention schema would reflect what a person is conscious of, while changes to the attention system would change what "bubbles up" to one's awareness.
