Zanata-cli doesn't detect xliff file as source when push

I'm trying to pussh a xliff file (version 1.2) to translate.zanata.org.

I'm getting always "No source documents found.".

I've tried adding rules for the extensions, add locales, nothing is working. Source directory name is ok too

This is the log:

<code>

I attached source file

File is correct since I can edit using other xliff editors.
