          (e.g. to build BER-friendly data structures using whatever
          Z39.50 toolkit is preferred.)
-       - Add javadoc comments for CQLNode and subclasses.
-       - Add the toPQF(Properties p) method to CQLNode and subclasses.
-               (### NOT YET FINISHED)
-       - Add UnknownQualifierException and UnknownRelationException.
+       - Add the toPQF(Properties p) method to CQLNode and
+         subclasses.  This produces a query in YAZ-style Prefix Query
+         Format, which can be trivially translated into a Z39.50
+         Type-1 query (see, for example, JZKit's code to do so).
+       - Add etc/pqf.properties to configure to toPQF() method.
        - Add "-p <props-file>" option to the CQLParser test-harness,
          indicating that the parsed tree is to be rendered to PQF.
-       - Add etc/pqf.properties to configure to toPQF() method.
+       - Add PQFTranslationException and its subclasses
+         UnknownQualifierException, UnknownRelationException,
+         UnknownRelationModifierException and
+         UnknownPositionException.
        - Rename ParameterMissingException to MissingParameterException.
+       - Add javadoc comments for CQLNode and its subclasses.
