- code refactoring to generalize attributes based on an OQL expression (friendly name, obsolescence flag, ....). The intermediate class AttributeComputedFieldVoid has been swept in favor of the use of a new method: IsBasedOnOQLExpresssion. - added an introspection API (experimental), allowing an external application to request for information about the capabilities of the framework (first step: list attributes and their main characteristics) SVN:trunk[4720]
