[xsd-users] error processing multiple schemas at once

[Eric Broadbent]

Hi Boris - indeed it looks like XSD/e is what I should be looking at.
The software system that consumes the XML is in fact an embedded system - I just didn't know that there was an XSD implementation designed for this.
I will transition to using that in my next iteration - and thanks so much for your help and advice.
