public abstract class NodeReferrerTag

extends CloudReferrerTag

A tag which is a 'NodeReferrerTag's is for example the FieldTag. A FieldTag must be a child of a NodeProvider. Originally, I named it 'NodeRefererTag' but this would have been a misspeling, though a common one. Cite from foldoc:

 From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]:

  referer

      A misspelling of "referrer" which somehow
     made it into the {HTTP} standard.  A given {web page}'s
     referer (sic) is the {URL} of whatever web page contains the
     link that the user followed to the current page.  Most
     browsers pass this information as part of a request.
