Hi @hlombard , thanks for this upload. That’s very useful and gives me a chance to look further.
I’m going to need to get back to you as I can see that the xsd parser I built on request before only works with complex types that are “in line” in the element definitions, rather than out-of-line. A solution to this could take a while to resolve and I’m going to be short of time this week. I will endeavour to look at it as soon as I can, as clearly that is a direction it needs to go in, but thought it best to manage expectations!
You may be interested in the following thread, as this is how the xsd implementation came about.
and also the following “documentation” I started to put together which isn’t quite complete, but I admit I have had to resort to reading it to remind myself…
