+# Notes on embedding values:

+#    emb          "Embed" embedding - normally /adm/wrapper but when

+#    wrp          "Wrap" - display using /adm/wrapper 
+#    prv          "Private" - like ssi, but always published private
+#    rat          "rat" - ?
+#    ssi          "Serve Side Include" - embeded by calling
