(note: Jira won't let me include this in the URL field at this time)

this defines permission-offline (for offline_access) but completely fails to mention permission-online (for online_access). Both should exist.

In addition, we my want to modify the  "Clinician Access for EHR Launch" capability set to include the use of permission-offline or permission-online.

In our system, permission-online is the most common access method used for EHR-launched SMART applications. Our tokens are also very short lived (15 minutes or less), so "single use" tokens aren't very useful, so the ability to declare support for this is very important.
