Description

In https://github.com/Polymer/polymer/pull/5125 we are fixing bindings to HTML attributes that have capitalization. The resulting change is the following:

Rather than the broken viewBox$="[[binding]]", Polymer will now automatically set an attribute when encountering viewBox="[[binding]]". This will only work if the attribute maintains capitalization. This is only the case for existing attributes, which mostly live in the SVG namespace: https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute

This clarifying note should probably be added to https://www.polymer-project.org/2.0/docs/devguide/data-binding#attribute-binding
