June Change Proposal: Definition of Tracking (ISSUE-5)

I would propose that we not define "tracking" within the TCS document. 

In the alternative, if the group elects to proceed with a definition, I would propose this small change:
> Tracking is the collection, retention, or use of data records that are, or can be, associated with a specific user, user agent, or device.

This definition encompasses collection of information, unlike the June Draft text.
