Rule

The metadata to be provided together with the ICAO data set shall be included in the same file as the data.

This approach is seen as acceptable given that the metadata will be of a relatively small size in comparison to the data itself.

This requirement means that the metadata is to be provided at the message level - the metadata requirements apply to the data set, not a feature or a timeslice. As the ICAO "AIP Data Set shall be valid against the AIXM 5.1.1 BasicMessage XMLSchema" (see AIXM version interoperability rule), the <aixm:messageMetadata> element needs to be used (as in the example).

Obviously, nothing in this requirement prevents the provision of more metadata.
