Subject: [PATCH] three problems exemplified by nasa.gov.  (1) Tidy options
 that will flesh out a piece of DOM even when there is nothing in it (2)
 prototype section for Option (3) pass the meta tags to the JS side so that
 they will be in document.head.childNodes and their content can be read by
 page JS
