EXCEPTION_INTERNAL_XML_ENGINE_ERROR – PB Docs 2021

Code Value: 14

This exception is thrown when an internal error occurs that
involves the XML engine used by PBDOM. PBDOM currently uses the Xerces
XML parser as the underlying device for processing XML documents and
for building up and sustaining the DOM tree.

There may be problems in the low-level XML parser engine, and if
one is encountered, this exception, which is rare, might be
thrown.
