<div class="block"><p>JAXB representation of an Xml Element.</p>
<p>This class represents information about an Xml Element from both the element
declaration within a schema and the element instance value within an xml document
with the following properties
<ul>
<li>element's xml tag <b><code>name</code></b></li>
<li><b><code>value</code></b> represents the element instance's atttribute(s) and content model</li>
<li>element declaration's <b><code>declaredType</code></b> (<code>xs:element @type</code> attribute)</li>
<li><b><code>scope</code></b> of element declaration</li>
<li>boolean <b><code>nil</code></b> property. (element instance's <b><code>xsi:nil</code></b> attribute)</li>
</ul>
<p>The <code>declaredType</code> and <code>scope</code> property are the
JAXB class binding for the xml type definition.
</p>
<p><b><code>Scope</code></b> is either <a href="JAXBElement.GlobalScope.html" title="class in jakarta.xml.bind"><code>JAXBElement.GlobalScope</code></a> or the Java class representing the
complex type definition containing the schema element declaration.
</p>
<p>There is a property constraint that if <b><code>value</code></b> is <code>null</code>,
then <code>nil</code> must be <code>true</code>. The converse is not true to enable
representing a nil element with attribute(s). If <code>nil</code> is true, it is possible
that <code>value</code> is non-null so it can hold the value of the attributes
associated with a nil element.
