Under the description of Collections, you might want to mention that
Collections can be made by combining two or more Collections with
boolean operations. Rather than saying collections use queries, you
might say Collections can contain all the items of a Kind, or filter
another Collection using a Python expression.
Collections don't always contain all items of a kind, nor a filter thereof.
That's just two examples.
A more appropriate statement would be to say that collections are based
off a Kind or off a ref collection and that collections can be combined
together using set arithmetic or filter expressions written in python.
Andi..
Good points. I completely rewrote that whole section sorta late last
night, discussing the various types of Collection.
Cheers,
