specifies a component which acts as a radio button as needed in HTMLForms.
Radio buttons are controls which can be grouped together, and in every
group, only one of the controls can be check. This means if one of them
is checked by a user interaction, all other controls in the same group
are automatically unchecked
Like in HTML, radio buttons are grouped together if and only if they have the
same name (see ::com::sun::star::form::FormComponent::Name).
contains a reference value which is used for submission in a HTML
form.
If the form the control belongs to is to be submitted (see
::com::sun::star::form::XSubmit), and the control is checked, this reference
value is used for submission.
specifies a value which is to be associated with the control when it's not
selected.
In various situations, the RefValue is associated with the control
if and only if it is selected. UncheckedRefValue provides a extensions of this concept: If present,
the value should be associated with the control when it is not selected.
