Element declararion

I am trying to specify some interfaces in Schema and met definite problems.

I'll be very thankfull if anybody could help me.

My question is, is it possible with a help of schema to declare that an 
element must NOT be empty?
As I searched through schema specification myself I could not find this 
possibility.

Thank you,
Nell G.
