As with elements, filters, etc. The new validators and transformers
will accept fully qualified package names starting with '+'.

elements:
  - name: foo
    validate:
      - +MyApp::Validate::TestFoo

The package just needs to implement a process() method, and die if the
validation fails.
And if you're using Catalyst-Controller-HTML-FormFu, you'll have
access to the context via $self->form->stash->{context}
