• Enhancement request (describe the enhancement being requested)
• Other (please ensure the description clarifies why the issue doesn’t fall into either of the above categories)

Descriptive summary

Inside tmx/TmxApi/tmx/pugixml we have committed the 1.7 src code of the pugixml parsing library (this version is 8 years old and we already include multiple xml parsing libraries). This XML parsing library is only used for the message_document.hpp which is not used anywhere. We need to remove this code from our source and either install this library as a debian package or replace any logic using it with a XML parsing library we already have.
