public class ProcessingInstruction
extends CharacterData

A JavaScript object for ProcessingInstruction.

Note: There is an architectural difference between the Java DOM layer and the JavaScript host layer: DomProcessingInstruction extends DomNode directly rather than a Java-equivalent character data class, whereas this JavaScript class inherits from CharacterData to correctly mirror the standard browser prototype chain.
