<shepazu> shepazu: Jeff may not have considered the issue of the
namespace of an element when he criticized using createElement as an
element method
I assume you mean that createElement() as an element method would
never need to have a namespace argument. Yes, I can see that - but I
still think that tweaking existing methods (createElement,
createElementNS) is better than inventing new methods UNLESS you plan
to have these new methods at the DOM Core level so that HTML coders
can use them too (not sure if that was the intention).
Even then it will be harder to re-train people and will be confusing
to tell them when to use Document.createElement() and
Element.createElement().
What I don't want though is different ways of creating SVG elements
than creating HTML elements ... thus my leaning towards both existing
techniques of innerHTML and document.createElement/NS.
