A customer of ours is using the Salesforce XML Parser to parse a deeply nested XML file. They are seeing the following error message:
I was able to reduce the "nested-ness" of the XML file for them (thus "fixing" the immediate problem), but we've never seen this error before and I can't find any official documentation of it. Is this an undocumented Salesforce limit, or are they perhaps using a third-party parser that has it's own limits? I'd love to find the documentation of this error so that we can reference it in the future (and watch for changes).
