The value will be made available to the validator property by means of ${label}. It does not
have any specific meaning to FormComponent itself.
Provide internal setter. We need this because people want to be able to chain together our
setters in FormComponent, etc. e.g. for .setLabel(foo).setRequired()
TODO: When we move to JDK5 and covariant return types, we can push this into ILabelProvider
and still make chaining in FormComponent work properly.
