Log message:
update to generateDS 1.6a

changes:

Version 1.6a (7/9/04, again)
  * Minor fixes.  Replaced dashes in names used as attributes (see
    cleanupName().

Version 1.6a (7/6/04, again)
  * For XMLBehaviors, implemented ability to retrieve
    implementation bodies for behaviors and for ancillaries
    (pre-conditions and post-conditions) from a Web address (URL).

Version 1.6a (6/30/04)
  * Added generation of behaviors.  An XML document can be used to
    specify behaviors (methods) to be added to generated sub-class
    files, including DBC (design by contract) pre- and
    post-condition tests.  See generateDS.html for more
    information on XMLBehaviors.

Version 1.5b (6/20/04, again)
  * Fixed handling namespace prefix in the XMLSchema file itself.
    generateDS.py now attempts to pick-up the namespace prefix
    (alias) from the "xmlns:" attribute on the "schema" element.

Version 1.5b (5/7/04)
  * Fixed several minor problems related to XML namespaces.
    Namespace prefix ignored when creating Python names (e.g. of
    classes and namespace prefix ignored during parsing.  That's
    about the best I know to do right now.
  * Fixed problems in generating code for names containing dashes.
    Now using underscore in place of dashes for Python names.

Version 1.5a (3/24/04)
  * Added keyword arguments to the generated factory functions.
  * Added generation of method "exportLiteral" and related support
    to export elements/instances to Python data structure
    literals.

Version 1.4c (3/10/04)
  * Element <complexType> in XSchema file not handled correctly.
    Fixed this so that when <complexType> is at top level, it will
    be handled the same way that an <element> is handled.  Note:
    We still have problems with <complexType> elements that are
    more deeply nested.

Version 1.4c (3/8/04)
  * Added ability to pass namespace abbreviation from the command
    line.  For example, the "-a" option enables you to replace
    "xs:" with "xsd:".

Version 1.4b (9/30/03, again)

    Python standard library.
