33 The formalism for attribute selection is the following:
34 - An empty set, or a set containing "*" will select all the dynamic
35 attributes passed to the object.
36 - A single "-" attribute will not select any of the dynamic attributes.
37 - A set of variables (without "-" as the first character of the
38 variable names) will select just the variables listed.
39 - A set of variable names, each prefixed by "-", will select all
40 variables but the ones listed.
