Description:
=========
When an XML document uses a DTD file such as <!DOCTYPE HDR SYSTEM "MLEP_HDR_11.DTD">  the DTD file must be placed in the same directory that the be-engine is run from or an error will happen.  See the "Symptoms" section  below for the error thrown if the file is not present. Also see the "Resolution" section regarding how to change this behavior.

Environment:
==========
All

When the DTD file is not present in the directory that be-engine was started from the following error happens:

Cause:
=====
The XPath.execute statement is reading the DTD file to validate the structure of the XML document.

Resolution:
=========
Change the DTD reference to:

<!DOCTYPE HDR SYSTEM "file:///C:/Logs/SR_1-BBI0VY/api2/MLEP_HDR_11.DTD">

This looks on the local host in the above directories.

Use of DTDs files in XML documents when using the XPath.execute function.
