Receive notification of a processing instruction.

<p>
The Parser will invoke this method once for each processing instruction
found: note that processing instructions may occur before or after the
main document element.
</p>

<p>
A SAX parser should never report an XML declaration (XML 1.0, section
2.8) or a text declaration (XML 1.0, section 4.3.1) using this method.
</p>

@param target
The processing instruction target.
@param data
The processing instruction data, or null if none was supplied.
