---------------------------------------
thanks for sharing the reports. I can see, that for all the examples you've
tried for memory profiling, the peak memory usage is about 125 Mb. But this
result is, when you've repeated the validation assessment 10000000 times. I'm
not sure, if this a poor memory management by Xerces (since the repetitions
were quite large).
The Xerces XSD 1.1 assertions implementation, uses DOM objects to implement the
XPath 2.0 XDM model (which is a given, due to internal design of PsychoPath
XPath engine) -- which I guess, leads to the implementation using more memory.
I see no easy way, of improving further the implementation quickly by design to
optimize memory management. Unfortunately, my response to this issue would be
"won't fix" due to the risks involved.
