| Developers using any web technology must take extreme care with APIs like [innerHTML](https://developer.mozilla.org/en-US/docs/Web/API/Element/innerHTML) and [insertAdjacentHTML](https://developer.mozilla.org/en-US/docs/Web/API/Element/insertAdjacentHTML) that directly manipulate DOM. If you use these APIs, you must guarantee that any HTML strings you pass to them are free from possibly malicious code. See the [MDN documentation on innerHTML](https://developer.mozilla.org/en-US/docs/Web/API/Element/innerHTML) for more info. | ||

| Polymer developers , an extra consideration applies to these APIs, in that we must also rule out the evaluation of untrusted custom element templates. |
There was a problem hiding this comment.
Eliminate "we" -- suggest maybe "Polymer developers must also guard against the evaluation of untrusted code in custom element templates."
