HIPAA edi/x12 XML wrapper question...

I have a trading partner that posts HIPAA x12 transactions to our servers. Those transactions are wrapped in XML

<?xml version="1.0" encoding="UTF-8"?>
<X12TRANSFER>transaction data</X12TRANSFER>

The problem is that on transfer the submitter is transposing ASCII characters, "&" becomes "&amp;" etc.

While each of the transposed characters is a valid individual byte the corresponding element is now 4 bytes longer which, at times, causes the element length to extend beyond the max element size. In essence we consider this transaction non-compliant and fail it accordingly.

Is anyone else familiar enough with HIPAA x12 to know something I don't? Should we assume all values like "&amp;" should be ";"?
