question: public final boolean supports ( String feature , String version ) { return implementation . hasFeature ( feature , version ) ; }
target:  Ask whether we support a given DOM feature. In fact, we do not _fully_ support any DOM feature -- we're a read-only subset -- so arguably we should always return false. Or we could say that we support DOM Core Level 2 but all nodes are read-only. Unclear which answer is least misleading. NON-DOM method. This was present in early drafts of DOM Level 2, but was renamed isSupported. It's present here only because it's cheap, harmless, and might help some poor fool who is still trying to use an early Working Draft of the DOM.
