Creating new shapes with "extra"properties

[Sarah Mount <mount sarah gmail com>]

Hi everyone,

Sorry if this is a daft question, but...

Is it possible when creating a new shape to create new properties that
go with that shape? For example, would it have been possible to
implement the UML - Class shape in XML?

If not, is it possible to "give" a new shape extra properties by
defining a Python plugin which would pop up a dialog box asking the
user to enter values for each custom property?

Thanks,

Sarah
