Polymorphic assign operator.
This should invoke operator= of the derived class.

inlineoverridevirtual |
Returns an XML tag name for this object as a root element.
We might want to give a different name for same externalizable objects, so this is used only when it is the root element of xml.

overridevirtual |
Reads the content of this object from the given XML element.
[in] | element | the XML element that represents this object |
Expect errors due to missing-elements, out-of-range values, etc.

overridevirtual |
Writes the content of this object to the given XML element.
[in] | element | the XML element that represents this object |
Expect only out-of-memory error. We receive the XML element this object will represent, so this method does not determine the XML element name of itself. The parent object determines children's tag names because one parent object might have multiple child objects of the same type with different XML element name.
