Re: Deprecated Attr methods

Here's a presentation on their data-binding:
https://www.youtube.com/watch?v=-dMBcqwvYA0&feature=youtu.be&t=12m39s

However, like I said, they allow this in their templates but do not write
it to the dom (they do not call .setAttribute or attr.cloneNode()).  So
it's not an issue for them.  But I think it's something that should be
considered to allow as others will want to do similar things and may want
to write to the DOM (as I do).
