DomRange

This construct enables a serializable representation of a DOM Range.

In a DOM Range object, the startContainer + startOffset tuple represents the start boundary point. Similarly, the the endContainer + endOffset tuple represents the end boundary point. In both cases, the start/endContainer property is a pointer to either a DOM text node, or a DOM element (this typically depends on the mechanism from which the DOM Range instance originates, for example when obtaining the currently-selected document fragment using the window.selection API). In the case of a DOM text node, the start/endOffset corresponds to a position within the character data. In the case of a DOM element node, the start/endOffset corresponds to a position that designates a child text node.

Note that end field is optional. When only the start field is specified, the domRange object represents a "collapsed" range that has identical start and end boundary points.
