Hm. It's worse than that: <form><template><form> will drop the inner 
<form>, because the form element pointer is set.

So, there's several ways we could fix this. We could simply say <template> 
isn't valid inside <form> and ignore the whole problem.

Or, we could have a form element pointer stack that parallels the 
template stack.

I guess the latter is best for authors. How do implementors feel about 
adding a new stack for the template stuff?
