* If you have a section format ID you can use it as a key to query

* is well-known and you can query the {@link PropertyIDMap} for PID
* strings. If you get back null you are on your own.
*
* This {@link java.util.Map} expects the byte arrays of section format IDs
* as keys. A key maps to a {@link PropertyIDMap} describing the
* property IDs in sections with the specified section format ID.
