Element is a class, but what is exported is a factory - a function generating class instances. Uppercase suggest that you need to instantiate something with new keyword (unless a decorator) which is not a case here.

Such a breaking change doesnt seem to be worth it imho, maybe there are better ways of handling this. Breaking change would require 2.0 release. If documentation is incorrect fix the documentation.
