Proposed resolution:

This wording is relative to N4842.

Add a paragraph at the end of [charconv.syn] as follows:

-?- The types to_chars_result and from_chars_result have the data members and special members specified above. They have no base classes or members other than those specified.
Add a paragraph at the end of [format.syn] as follows:

-1- The class template format_to_n_result has the template parameters, data members, and special members specified above. It has no base classes or members other than those specified.

To ensure that to_chars_result, from_chars_result, and format_to_n_result can be used in structured bindings, they need the special wording we use to negate the general library permission to add private data members and bases.
