This table is for DOM class packages, but not for KParser.
If you like to know what were tested, see 't/tester.t'.
I am going to settle the supported classes and methods once as follows, and get rid of the word 'beta'.

Fundamental Interface	Status
DOMException	NOT SUPPORTED (No exception assumed)
DOMImplementation	Do not expect that you can get TRUE from 'hasFeature'.

NodeList	PASSED MY EASY TEST
NamedNodeMap	PASSED MY EASY TEST
CharacterData	PASSED MY EASY TEST ('substringData', 'appendData' , 'insertData', 'deleteData', 'replaceData' : NOT SUPPORTED)
