...interesting related and *relevant* experience

my whole  point is: it might be really worth to leverage on the 
existing DBC/XML software infrastructure API/protocols, and then try to 
be compliant as much as possible - instead of designing yet another 
programming language, API and protocol stack. This would also make our 
specs thinner, smaller and easier to implement. Again, simplicity vs. 
completeness...

cheers
