Allow maintaining templates inside an element without Polymer stripping the content

[MaKleSoft]

As a followup on #144, is there a way to tell Polymer to not strip the content of a template element? I understand that I can still access the content via the ref_ property but the property name suggests that it is not intended to be used that way and relying on it might break my app at some point.

We recommend you avoid this type of construction and instead place a template that you want to use outside of a data-binding context outside of the element's bound template. Here's one way to do it:

This way you can easily avoid having to deal with the ref concept.

Thanks! But I can think of at least one scenario where this won't work. Let's say we want the template to be passed in from the outside:

Now the template is inside the binding context of the parent element, and I don't see a way of avoiding that.

Nice example, Martin. Illustrates the problem nicely.
Would something like this work: http://jsbin.com/nimohiralega/4/edit

Also you can pass a "model" and "bindingDelegate" if you would like to make {{ bindings }} work inside of that template.

That's the disadvantage of my suggestion, too: createInstance will process {{ bindings }} whether you want it to or not. However, that's unavoidable since it was already inside another polymer-element's template, so the {{ bindings }} already had meaning.
