 <h1>Introduction</h1>
 <p>
 This proposal describes how support for "data linking" can be added to the jQuery core library. The term "data linking" is used here to mean "automatically linking the field of an object to another field of another object." That is to say, the two objects are "linked" to each other, where changing the value of one object (the 'source') automatically updates the value in the other object (the 'target').
