This test page uses the try and catch
exception handling in ECMAScript Edition 3 (3d edition of
ECMA-262), which is still not final as of October 1999. It is
therefore separate from all the other test pages.
This page does not test WRONG_DOCUMENT_ERR, NO_MODIFICATION_ALLOWED_ERR, or DOMSTRING_SIZE_ERR anywhere in the DOM Level 1 Core. It tests all other exceptions mentioned in the DOM Level 1 Core (nowhere near exhaustively, though). The tests for NamedNodeMap exceptions do not test anything with attributes where specified==false.
