Description

Dear maintainers

I'm looking for the ability to output xml files from Flink Table API, just like csv and json already supported formats.

To me, a new format could be required to make the appropriate serialization. Am I missing any existing feature (or duplicate issue) that could allow it without a dedicated format?

Depending on your returns and if it makes sense, I could get involved in writing the appropriate format based on the same logic as `JsonRowDataSerializationSchema`.

Best regards
