[xsde-users] Polymorphic data model and custom binary streams -- doe not seem to work right.

[Nikita Visnevski]

Boris,

it is actually funny to me that nobody asked this from XSD/e.  The whole reason why I need it is because the experimental code that I am writing needs to run on the real-time embedded device, and compressing xml streams is exactly what I need in this application.  I want the data exchange packets going to and coming from the device to be as small as possible.  It is a bit counter-intuitive to me that people wanted it in XSD, but not in XSD/e.

I will give it a thought and let you know.

Thanks
