    def writeXML ( self, parent ):
        '''Generate the XML for all codes in the symbol table.
        '''

The purpose of this method is to build two subtrees of the output XML: one for valid codes, and one for collision codes. We can do both in one pass through the symbol table.

        #-- 1 --
        # [ parent  :=  parent with an rnc.ABBR_SET_N node and an
        #       rnc.COLLISION_SET added
        #   abbrSetNode  :=  that rnc.ABBR_SET_N node
        #   collSetNode  :=  that rnc.COLLISION_SET_N node ]
        abbrSetNode = E ( rnc.ABBR_SET_N )
        parent.append ( abbrSetNode )
        collSetNode = E ( rnc.COLLISION_SET_N )
        parent.append ( collSetNode )

The logic that generates the XML for the various bindings is given in their .writeXML() methods. Section 27.6, “StdBind.writeXML()” and Section 28.7, “EqBind.writeXML()” generate abbr nodes; Section 29.7, “CollBind.writeXML()” generates a collision node.

        #-- 2 --
        # [ abbrSetNode  :=  abbrSetNode with new rnc.ABBR_N
        #       elements added for entries in self for valid
        #       codes
        #   collSetNode  :=  collSetNode with new rnc.COLLISION_N
        #       elements added for entries in self for
        #       collision codes ]
        for sym in self:
            if isinstance ( sym.binding, CollBind ):
                sym.binding.writeXML ( collSetNode )
            else:
                sym.binding.writeXML ( abbrSetNode )
