Cancelling W3C CCG meeting May 21, 2019

Cancelling this CCG meeting because we have no topics scheduled.

Reminder that our 1-week countdown for this proposed work item started on
last Tuesday's call, so please give any feedback before this coming Tuesday
(on the issue or the mailing list). If we need to discuss the feedback, we
can do so on the following call.

Thanks,
