    Properties are very useful tools for tagging your Zope objects
    with little bits of data or information.  In conjunction with
    methods and scripts, properties make extending simple objects like
    Folders a very powerful technique.

       You haven't mentioned here that the "selection" and "multiple selection" property types require method names
       rather than literal data. Perhaps it would be useful to give an example of a method being used for this task,
       even if the example is placed in a chapter on scripting and mentioned here only as a "see the section [name]
       for an example".

       It is a *very* bad idea to represent money amounts with floats. You'll likely end up with rounding errors!
       You'll much better be using longs for that purpose, e.g. counting the cents instead of counting the dollars.
