The result of parsing drives these callback methods. The open and close actions should be balanced. The flush method will be the last method called, to give the receiver a chance to flush any pending data into the document.

Refer to DocumentParser, the default parser used, for further information on the contents of the AttributeSets, the positions, and other info.
