Howard,

You are right that one can read every thing from the schema, but given there 
are manual pages, it would not be too much work to put the most essential facts 
there. I know that developers don't like to write manual pages, and it can be a 
frustrating experience to realize that most users won't read them. Still I 
believe in manual pages 😉

Kind regards,
Ulrich Windl
