/**
* The deserialize method is called during xml parsing.
*
* This method is called statictly, this is because in theory this method
* may be used as a type of constructor, or factory method.
*
* Often you want to return an instance of the current class, but you are
* free to return other data as well.
*
* You are responsible for advancing the reader to the next element. Not
* doing anything will result in a never-ending loop.
*
* If you just want to skip parsing for this element altogether, you can
* just call $reader->next();
*
* $reader->parseInnerTree() will parse the entire sub-tree, and advance to
* the next element.
*
* @param Reader $reader
* @return mixed
