Hi Curt,

I think that L3 Core test case wellformed04 is incorrect in assuming that
no errors will be reported after normalizing document with 'well-formed'
set to false..  This is because the createAttribute and setAttribute
methods are used rather than the createAttributeNS and setAttributeNS
methods (if you refer to the correctly written wellformed02, the equivalent
test case of wellformed04 is performed with an element node rather than an
attribute node, however the DOM Level 2 methods (createElementNS) are
used).

Since the attribute created in wellformed04 has its local name and prefix
null, this is a DOM Level 1 node, and an error should be reported, though I
may be incorrect.
Reference:
http://www.w3.org/2004/02/PR-DOM-Level-3-Core-20040227/namespaces-algorithms.html

Below are the minor modifications I suggest to this test case.

<assertDOMException id="xml10InvalidName">
      <INVALID_CHARACTER_ERR>
            <createAttributeNS var="attr" obj="doc"

namespaceURI='"http://www.example.org/domts/wellformed04"'
                        qualifiedName='"LegalName&#2190;"'/>
      </INVALID_CHARACTER_ERR>
</assertDOMException>
<try>
      <xmlVersion obj="doc" value='"1.1"' interface="Document"/>
      <catch>
            <DOMException code="NOT_SUPPORTED_ERR">
                  <return/>
            </DOMException>
      </catch>
</try>
<setAttributeNS obj="docElem"
namespaceURI='"http://www.example.org/domts/wellformed04"'
                        qualifiedName='"LegalName&#2190;"' value='"foo"'/>
<xmlVersion obj="doc" value='"1.0"' interface="Document"/>
.

Thanks in advance,
