That is actually quite a useful axis of distinction. If we want normal 
methods on the document like getElementsByClassName or getElementById to 
return elements in templates they obviously need to be parsed as actual 
elements in the DOM. If we don't it seems very unnatural to have them 
parsed as elements; making DOM Core methods, CSS selectors, etc. have 
some dependence on whether there is an element called <template> in the 
tree just seems like a recipe for pain.

My feeling is that the elements in templates aren't like the other 
elements in the document and so we don't want the normal 
lookup/traversal methods on document to work on them.
