1.  Introduction

   This specification adds mechanisms to the Atom Syndication Format
   which publishers of Atom Feed and Entry documents can use to
   explicitly identify Atom entries that have been removed.

2.  Notational Conventions

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in [RFC2119].

   This specification uses XML Namespaces [W3C.REC-xml-names-19990114]
   to uniquely identify XML element names.  It uses the following
   namespace prefix for the indicated namespace URI;

    "at": "http://purl.org/atompub/tombstones/1.0"

3.  The at:deleted-entry element

   The at:deleted-entry element represents an Atom Entry that has been
   removed.

     deletedEntry =
       element at:deleted-entry {
         atomCommonAttributes,
         attribute ref { atomUri },
         attribute when { atomDateConstruct },
         ( element at:by { atomPersonConstruct }?
         & element at:comment { atomTextConstruct }?
         & element atom:link { atomLink }*
         & element atom:source { atomSource }?
         & anyElement* )
      }

   The at:deleted-entry element MUST contain a ref attribute whose value
   specifies the value of the atom:id of the entry that has been
   removed.

   The at:deleted-entry element MUST contain a when attribute whose
   value is an [RFC3339] "date-time" specifying the instant the entry
