Suppose I use XBL2 to define <fancycontainer>, a container with elaborate
styling that I can't do with CSS alone. Changes to the children of a
<fancycontainer> need to be reflected in the shadow DOM tree built for
<fancycontainer>, otherwise dynamic changes in the presence of
<fancycontainer> are just broken. For example, adding a child to <container>
would need to find the associated template instance and insert the child
into the right place in the instance.
