The type attribute is for giving the *type* of data, not for indicating
what it's used for. RFC3106 deals with auto-fillout.

   # Some names (all starting with the string "Ecom_") in this version of
   # HTML forms have predefined meanings, allowing UAs to fill in the form
   # fields automatically. These names, and their semantics, are described
   # in [RFC3106].

(We should probably get that expanded to handle WF2 controls, though.)
