An identifier, automatically generated by the early NeXT web editor.
An obsolete element from ancient editions of HTML, specifying document metadata about which link ids have already been used, so they would not be re-used even if deleted in the future. More generic metadata mechanisms exist today.
For a history and description of this element, see Working NEXTID Tag Element Example by Griff Ruby.
This element can be used only within the head element.
