/**
* Inspects the given Object and type and returns the result as a DOM Element.
*
* DomInspector is an optional interface that enables an optimization. Like
* most optimizations it unfortunately adds some complexity. The basic idea is that, whilst XML is a
* great lowest-common-denominator for the Inspector interface (perfect for passing
* between disparate technologies and tiers in order to allow maximum flexibility in what can be
* inspected) serializing to and from XML strings is expensive.
*
* Most Inspectors maintain their inspection results internally in a DOM. This interface allows them
* to expose that DOM directly, rather than serializing it to a String, whereupon either the
* Metawidget or a CompositeInspector must typically deserialize it back again.
*
* If your Inspector extends BaseObjectInspector or
* BaseXmlInspector, this optimization is implemented for you.
