What is a functional language?

There are two main properties:
	1: No assignments, no side effects, referential transparency,
           or whatever you call it.
	2: Higher order functions.

BUT: Is property no. 2 just a nice feature or do you regard it as nessecary for
     a language to be called 'functional'? Does any formal definition?
