Interesting. I just tried and got the same result. I guess I never even
tried to do this, given that I knew lxml won't support it anyway...

Without debugging into this, it seems that expat raises that exception
before ElementTree even gets to handle the unknown entity.

I just found this post, but didn't try it:
