Re: [xml-dev] Use DTDs!

["G. Ken Holman" <gkholman@CraneSoftwrights.com>]

The same thing happened with Microstar's Near and Far DTD management 
tool.  It became essentially uni-directional from DTD to 
display.  No-one could use it for production maintenance because the 
author's entity structure and source expression evaporated.

The mistake discovered on day two of the product was the thinking 
that users would want to use the graphical tool for *all* of the DTD 
maintenance.  If it had been perceived correctly that users needed to 
preserve their own concept of internal modularization, declaration 
ordering, commenting, etc., the product would have been designed 
differently from the ground up and found a more appropriate role in 
the augmentation of the development/maintenance process and not try 
to be the be-all and end-all of model building.

Peter Flynn's recent legacy project discussion has revealed that more 
than 20 years later the product is still being used for 
visualization.  And I think Tommie's coining of the term "DTD scat" 
still gets used (forgive me if it was one of Tommie's colleagues who 
came up with the term).
