On a somewhat related note :
Has anyone done any comparisons between the ideas and mechanisms in the ISO
STEP
standard including the EXPRESS modeling language and XML? 

[ I am relatively new to XML, my SGML experience dates back to the early
90s.
  I spent the last couple of years in the CAD industry. I am still ignorant
  enough about XML to think that STEP is more mature in certain areas, and 
  that we should learn from some valuable lessons experienced in that
domain. ]
