XLIFF 2.0 OpenXML Filter bad XLIFF file generated

Hi, I'm trying to generate an XLIFF 2.0 file from a DOCX document. But I'm encountering an issue with the generated XLIFF file. Its content is always incorrect, regardless of the complexity of the DOCX file.

Here is the xliff2 output: bad_xliff2_output.xliff

Here is the docx input file: simple_word_doc_en.docx

You can take a look of the code I did

To solve this, I extended the OkpToX2Converter class and overrode its public documentPart method.

Coul you help me to solve this problem?

Best Regards,
