I think the W3C spec is 80% right in not specifying
it: language neutrality is a major goal.
Unfortunately it's not quite as clear cut as all that,
and your code fragments illustrate the problem.

This code isn't vendor neutral: it relies on a DOM
vendor specific (MS I presume) Document creation
mechanism. Vendor neutrality is another important goal,
and that's not addressed by the Level 1 spec.
