To be clear, it's not in the Process document as a general statement about
requirements or conventions for other W3C documents. It's simply a statement
in the "Status of this Document" of the Process document itself, And the
scope of it is restricted to just the Process document itself. It's clearly
not intended to express or imply any convention for other W3C documents.
