I experimented by modifying Base.js:
- added Record.newPlainClass, Record.newNodeClass, Record.newClass
- modified Record.newPlainInstance, Record.newNodeInstance and
Record.newInstance
Quick test with Record.newPlainClass and Record.newPlainInstance worked.
The modification is on SVN revision 2415 and it potentially breaks
something because I changed the signature of Record.newInstance.
