Document Object Model (DOM) Conformance Test Suites
Since domino doesn't implement deprecated DOM features some tests are no longer relevant. These tests have been moved to the obsolete directory so that they are excluded from the suite.
Attributes vs. Nodes
The majority of the excluded level1/core tests expect Attributes to inherit from the Node interface which is no longer required in DOM level 4. Also Element.attributes no longer returns a NamedNodeMap but a read-only array.
Obsolete Attributes
Another big hunk of excluded tests checks the support of reflected attributes that have become obsolete in HTML 5.
