Test cases I can think of that we would need:

1.  Test null:id vs. xml:id, which wins when both are defined?
2.  Test multiple xml:id's (the parser will throw an error, i'm pretty sure)
3.  Test xml:id in HTML (we should probably ignore it)
4.  Text xml:id attribute normalization
  a. get the value via js (getAttribute, getAttributeNS, other ways?), which
are normalized?
  b. set the value via js, see that it's properly normalized
  c. use getElementById to find normalized names.  should getElementById
normalize its args?
5.  Possibly test lookup across documents.  an HTML document embedding an XML
document, calling objectElement.contentDocument.getElementById() how is
normalization handled, etc.

I think that's all we need to start with.  Writing those test cases will
probably take longer than adding the support into Element.cpp, and adding the
attribute name into xmlnames.in. :)

It's possible that Hixie or others have already made some of the tests we might
need.  Heck, the W3c might even have a test suite for xml:id (I kinda doubt
it).
