public interface UniqueIdVendor
UniqueIdVendor is an
interface implemented by UIComponents
that also
implement NamingContainer
so that they can provide unique ids
based on their own clientId. This will reduce the amount of id
generation variance between different renderings of the same view and
is helpful for improved state saving.
