[Seaside] [Magritte] Multiple descriptions validation/condition

[Humber Aquino]

Hi everyone!

I have a question about validating models with Magritte.
When i add a condition to a magritte's description, the condition
references the value. For example:

SomeClass class>>descriptionFoo
  ^ (MAStringDescription
            auto: 'foo
            label: 'Foo'
            priority: '10')
              addCondition: [:value | some value checking]
              labelled: 'Invalid something';
              yourself.

In SomeClass i have many descriptions and i want to do some
validations combining two or more descriptions.
I don't know if this is the way to do this.

Thanks in advance :D
