Title: Missing attribute 'original'

I copy pasted the example messages.en.xliff provided. Running it on symfony 2.6 required me the attribute 'original'.
I added ' original="file.ext" ' as attribute for the file tag and it worked. However I am not shure about the proper parameter for this attribute.
