- Access to Caret, Selection, Grammar errors, spelling errors
  - Frank provide feedkback on discussion with IE team about introducing
tags that covers these vs. APIs.
  - Is API access to a contenteditable section preferred?
  - We need to decide if we stick with going after API changes to get this
information or use tags or a combination thereof
- Steps to assess what HTML elements are allowable in the shadow DOM
   - Review Charles' canvas element change proposal (attached). Is turning
off initialization sufficient for elements like Frame and IFrame?

- Action Item Frank: what API does IE use to track content selection and
carets in content editable areas?

Reference Material APIs:
- Browser API Comparisons for Caret Tracking and Content Selection:
- Getting the selection object:
- sel = window.getSelection() //sel is a Selection object
- rangex = sel(0);
- rangex.collapsed(); //If it is collapsed it is a caret
- reangex.collapse();

Reference: revisions to 2D Context API - modifications
