* Parser handler for JDO XML MetaData.
* Caters for "JDO", "ORM" and "JDOQUERY" XML MetaData.
* Implements DefaultHandler and handles the extracting of MetaData for JDO from the XML elements/attributes.
* This class simply constructs the MetaData representation mirroring what is in the XML MetaData file.
* It has no knowledge of the class(es) that it represents, simply the information in the XML MetaData file.
* The knowledge of the classes is imposed on the representation at a later stage where necessary.
*
* Operates the parse process using a Stack. XML MetaData components are added to the stack as they are encountered and created.
* They are then popped off the stack when the end element is encountered.
