Revision 400531 of ProcessingInstruction

<p>{{ DomRef() }}</p>
<p>A processing instruction provides an opportunity for application-specific instructions to be embedded within XML and which can be ignored by XML processors which do not support processing their instructions (outside of their having a place in the DOM).</p>
<p>A Processing instruction is distinct from a <a href="/en/XML/XML_Declaration" title="en/XML/XML_Declaration">XML Declaration</a> which is used for other information about the document such as encoding and which appear (if it does) as the first item in the document.</p>
<p>User-defined processing instructions cannot begin with 'xml', as these are reserved (e.g., as used in &lt;?<a href="/en/XML/xml-stylesheet" title="en/XML/xml-stylesheet">xml-stylesheet</a> ?&gt;).</p>
<p>Also inherits methods and properties from <a class="internal" href="/en/DOM/Node" title="En/DOM/Node"><code>Node</code></a>.</p>
