Use this method to deserialize an object from a SimTK::Xml::Element.

The element is assumed to be in the format consistent with the passed-in versionNumber. If there is a file attribute in objectElement it will be ignored; if you want it processed you should call readObjectFromXMLNodeOrFile() instead.

Reimplemented from OpenSim::Object.
