Section 16.3.1: is a specification required for non-permanent field registrations?

[reschke]

Registration requests consist of at least the following information:
[...]
Specification document(s):
Reference to the document that specifies the field, preferably

If the registration consists of "at least" a group of information that
includes a specification document, doesn't that mean the policy is
always "Specification Required", not just for permanent registrations?

[mnot]

I think the intent here was to encourage but not require a specification for provisional registration. Will PR.
