What about:
  Security Considerations
  None. multipart/form-data introduces no security considerations.

	Content-form-field
instead of 
	Name

yes, that's the idea.

The goal wasn't to create a variant use but to adopt whatever
content-length was used for in email and HTTP. (They *are* the same,
aren't they?) In the case where C-T-E is binary (as it is in HTTP),
the canonical form and the encoded form of the body part are the same.
