Netscape/Mozilla actually supports a fair chunk of the specs mentioned,
but not completely which is why it reports not supported. Here are
the/some reasons why Netscape does not return true for these:
Ken Sall:
>NS supports DOM Level 2 except for 3 areas:
>- UIEvents: basic user interface events
Missing the activation event.
>- MutationEvents: events for mutations in a DOM tree
Probable missing things:
a. The event that fires on all subnodes whenever a hierarchy enters or
leaves the document.
b. Perhaps missing subtree modified events, and stuff caused by that.
>- Traversal: Alternative traversal methods of a DOM tree
TreeWalker implemented, but not the NodeIterator.
There are probably bugs logged on all of these issues in mozilla.org's
Bugzilla if you are interested.
