9. A data processing system for email change tracking, the data processing system comprising: a bus; a memory connected to the bus; a persistent storage connected to the bus, wherein the persistent storage contains computer executable instructions thereon; a display connected to the bus; a communications unit connected to the bus; and a processor unit connected to the bus, wherein the processor unit executes the computer executable instructions to: receive an email having a change tracking annotation defining an annotated portion within the email to form a received email, wherein the received email includes a set of tags comprising start and end tags defining an annotated portion, wherein the tags of the annotated portion comprise tags from a set of comment tags; parse the received email with a first parser, the first parser ignoring the annotated portion to form a parsed first portion portion and wherein the tags of the annotated portion are ignored by the first parser; parse the annotated portion of the email with a second parser capable of parsing the annotated portion to form a parsed annotated portion, wherein the tags of the annotated portion are parsed by the second parser; and display the received email comprising the parsed first portion and the parsed annotated portion, wherein the parsed annotated portion includes email change tracking indicating changes in a text that occurred at each location of each text change to a user.

The data processing system of claim 9 , wherein the processor unit executes the computer executable instructions to parse the received email with a second parser comprises: a capability of selectively and programmatically enabling the capability of the second parser to parse the annotated portion.
