025/**
026 * Method annotation used for methods that should be invoked when the page is detached at the end of a request, before
027 * it is returned to the page pool for later reuse.
028 *
029 * PageDetached methods should take no parameters and return void. They must either have this annotation, or be named
030 * "pageDetached".
031 *
032 * To be clear: methods with this annotation (or name) are still invoked even in Tapestry 5.2, which does away with the
033 * page pool.
