The requisite standards require .nodeName to provide a node's name in upper case.

Presumably this depends on whether the document is HTML or XML?

On checking the standard, actually, yes. XML/XHTML preseves case; HTML to-uppers. I did not know that.

And I'm in XML, so the bug I thought I saw ... isn't.

Nevermind.
