NOTE: This method is now obsolete.
not used anymore - ObjectsNamespaceParser will be dropped with 2.x, use ObjectDefinitionParserHelper instead
Parse the specified XmlNode and decorate the supplied ObjectDefinitionHolder, returning the decorated definition.
The decorated definition (to be registered in the IApplicationContext/IObjectFactory), or simply the original object definition if no decoration is required. A null value is strickly speaking invalid, but will leniently treated like the case where the original object definition gets returned.
Implementations may choose to return a completely new definition, which will replace the original definition in the resulting IApplicationContext/IObjectFactory.
The supplied ParserContext can be used to register any additional objects needed to support the main definition.
