/**
* The <code>DOMCharacterData</code> interface extends DOMNode with a set of
* attributes and methods for accessing character data in the DOM. For
* clarity this set is defined here rather than on each object that uses
* these attributes and methods. No DOM objects correspond directly to
* <code>DOMCharacterData</code>, though <code>DOMText</code> and others do
* inherit the interface from it. All <code>offsets</code> in this interface
* start from <code>0</code>.
* <p>As explained in the DOM spec, text strings in
* the DOM are represented in UTF-16, i.e. as a sequence of 16-bit units. In
* the following, the term 16-bit units is used whenever necessary to
* indicate that indexing on DOMCharacterData is done in 16-bit units.
* <p>See also the <a href='http://www.w3.org/TR/2000/REC-DOM-Level-2-Core-20001113'>Document Object Model (DOM) Level 2 Core Specification</a>.
