The current main constant for XML Processing leads to potentiel app crashes #21

Running a heavy load on the app currently leads to crash of the app, specifically as we multiprocess.

Fatal error: StackOverflowError: Enabling the yellow zone of the stack did not make any stack space available. Possible reasons for that: 1) A call from native code to Java code provided the wrong JNI environment or the wrong IsolateThread; 2) Frames of native code filled the stack, and now there is not even enough stack space left to throw a regular StackOverflowError; 3) An internal VM error occurred.

I have a feeling this might be due to the same XML Processor being used by all documents as they are processed together, which will require a major rewrite of the library.
