/**
* The {@code } tag renders an HTML 'input' tag with type 'radio'.
*
* Rendered elements are marked as 'checked' if the configured
* {@link #setValue(Object) value} matches the {@link #getValue bound value}.
*
*
A typical usage pattern will involved multiple tag instances bound
* to the same property but with different values.
