* <p>This {@link Binding} specifies a {@link LongDescriptor}.</p>
*
* <p>An long descriptor is defined by a <b><code>{@literal <long>}</code></b> xml element.</p>
*
* <p>This element can have an attribute "name", which specifies the name of the created object in the WireContext.</p>
* <p>This element must have an attribute "value", which specifies the value of the object.</p>
*
* <h3>Example</h3>
*
* The following Xml declaration will create a Long 'l', with the value '42'.
* <pre> <objects>
* <long name='l' value='42' />
* </objects></pre>
