You can show or hide a form on a page by giving it a "rendered=" attribute value that is an EL expression referencing a boolean property on a backing bean. When that property is true, the form renders. When it is false, the form is hidden.
"privilege" comes from the Latin words for "private" and "law" (legal) and dates to feudal times. To "claim privilege" meant that you were above the laws that applied to the common people.
