Sybase PowerDesigner Data Architect

I've been using this tool for a number of years. I'm using verion
6.1.3 and it meets my needs when it comes to PostgreSQL development.
I recently found the "PowerDesigner Definition File Library" at
http://www.datamodel.org/PowerDesigner/progress.def. Alain Lavigne
has created a definition file for version 7 of PowerDesigner, but I
am creating one for version 6.

I have used SQL Anywhere 5.5 as the starting point. The first thing
I did was turn off EnableAscDesc so that CREATE INDEX commands do not
include the ASC or DESC options:

EnableAscDesc = NO

The two remaining problems are:

- default values are always enclosed in single quotes (') which is
fine for character fields but not for anything else.

e.g

create table security_notice
(
id T_ID not null,
date_added timestamp not null
default 'current_timestamp',

- remove key name from foreign keys

alter table element_pathnames
add foreign key FK_ELEMENT__REF_11730_ELEMENT (element_id)
references element (id) on update cascade on delete cascade;

Has anyone already done this?
