description of "plan resource" does not say you can use HTTP DELETE to delete a plan resource

In Section 5.5 of CAMP 1.1 we state that:

"Providers SHALL support the HTTP GET, PUT, and PATCH methods on all of the resources defined in this section. [RE-53] Requirements for the support of additional HTTP methods are outlined in the descriptions of each resource below."

For the "assembly" and "component" resources we require that providers support the DELETE method to remove the resource (requirements RE-61 and RE-62 respectively), but nowhere do we state that providers must support the DELETE method on "plan" resources.
