/**
* whether another property is present or not.
*
* <p>
* Sometimes you'd want to map a Java primitive type to an
* to represent the absence of the property, thus you always
* end up producing the value when you marshal to XML.
*
* For example,
* <pre>
* {@link XmlElement}
* class Foo {
* {@link XmlElement}
* int x;
* }
*
* marshaller.marshal(new Foo());
* </pre>
* and you get:
* <pre><xmp>
* <foo><x>0</x></foo>
* </xmp></pre>
*
* <p>
* you can indicate the absence of the property by setting this boolean
* to false.
* <pre>
* {@link XmlElement}
* class Foo {
* {@link XmlElement}
* int x;
* {@link XmlIsSet}("x")
* boolean xIsPresent;
* }
*
* Foo f = new Foo();
* f.x = 5;
* f.xIsPresent = false;
*
* marshaller.marshal(f);
*
* <xmp>
* <foo/>
* </xmp>
*
* f.xIsPresent = true;
* <xmp>
* <foo><x>5</x></foo>
* </xmp>
* </pre>
*
* <p>
* as {@link XmlElement}, {@link XmlAttribute}, {@link XmlValue}, or {@link XmlElementRef},
* ...<b>TBD</b>.
*
* @deprecated
* this hasn't been implemented in the RI, and this hasn't been speced yet.
* I believe Joe asked for this feature. I'd like to drop this.
