Some mapping formats do not include the descriptor of fields since they assume all fields are uniquely identified by name.
This kinda sucks because unless we do a lot of additional lookup work <i>(Which may not even be successful)</i>,
we're missing out on data. If this is ever the case formats that do require this data cannot be exported to.

@return {@code true} when there are field entries in these mapping which do not have descriptors associated with them.
