A problem related to the current setup is how to get the <DOCTYPE> tag as
the first line in an html document. I am not as comfortable with ECS
internals as others and have not looked at all at how xml is being handled,
so I was reluctant to do go very far from the current arrangement to get
doctype working. I could not come up with a way to get it added as Document
is a wrapper around an html object (I thought after seeing this that
Document was not xml related). It seemed it would be necessary add lots of
code to the output method instead of just calling html.output(). Hopefully,
your solution to your xml concerns could help with my html problem?
