--  documents using the XPath query language.

     (N     : Dom.Core.Node;
      -- A node in the XML tree against which the XPath query is

     ) return Dom.Core.Node_List;
   -- Apply an XPath query, starting with the given node, in the case
   --  of a relative XPath query, or the document that contains the
   --  given node, otherwise.  Returns a list of nodes, which may be
   --  empty, that meet the XPath specification.  If the query does
   --  not follow XPath syntax, the Malformed_XPath exception is
   --  raised.

   Malformed_XPath : exception;
   -- Raised when the XPath query does not conform to XPath syntax.

   Inappropriate_Node : exception;
   -- Raised when the starting node does not correspond to the type of query
