So my feeling is that the tricky part of this is that given that a template
deserializes by lifting elements into its content DF, it stands to reason that
the reverse would be true. E.g. It seems desireable to retain the following:

document.documentElement.innerHTML = myMarkupString;
var output = document.documentElement.innerHTML;
assert(output == myMarkupString).

This suggests to me that template.innerHTML should parse the markup using
implied context parsing, and
replace its content DF with the resulting DOM.


I think that childNodes, appendChild, etc... should not delegate to the content
DF. E.g. though would behave much like <script> by simply appending children to
the template, but not affecting its content.

Serializing a <template> which both direct children and content would result
similarly to <script>. E.g.

<script>var i = 1;</script>

var i = document.getElementById('foo');
var div = i.appendChild(document.createElement('div'));
div.innerHTML = 'bar';
i.innerHTML // var i = 1;<div>bar</div>
