[0.9] hidden$="{{isHidden}}" vs hidden=$"{{isHidden}}"

[gertcuykens]

The second one is much more easier and faster to read for humans, is it technically possible or are we talking html violation here?

hidden$="{{isHidden}}"
hidden=$"{{isHidden}}"

I can also live with this
hidden="${{isHidden}}"

hidden=${{isHidden}}

The only reason we use this syntax is because IE validates and will excise any invalid attribute content (like {{) for certain attributes like href and style before Polymer ever gets to see it. Using $="..." is a workaround, since the attribute name becomes href$ and is thus not validated. It is an ergonomic compromise for cross-platform capability.
