The error message can be seen in Travis build 99

Would please allow XML comments? It could help organize the training and test data sets

It should be possible https://stackoverflow.com/questions/18313818/how-to-not-load-the-comments-while-parsing-xml-in-lxml, it will need to be changed in parserator.

Today XML comments are working fine
