Language structure to XML conversion performs whitespace processing and entity reference expansion while generating the XML document. Entity reference expansion increases the length of data which is included as element content causing it to grow up to 6 times the original length of the data (the longest predefined entity is 6 characters long).
Ensure that the language structure has not changed since the Language structure to XML converter has been generated. Regenerate the XML converter if changes have been made to the language structure.
