equivalent of "NOT NULL" in schema?

Hello, I'm new to Schema, so if this question is not appropriate for  
this list, please let me know.

We're using SOAP to transfer data from one database to another.  I'm  
in the process of working out a Schema definition which allows us to  
validated the SOAP response as much as possible before attempting  
inserts into the database.  I'm curious what the best way to define a  
type which implies "NOT NULL", specifically, that an element must  
have at least one character present for whatever data type it is.   
Clearly this can be done with multiple restrictions on minLength of a  
simpleType, but is there any way to "inherit" from a "not null" type  
in the Schema to where a string or integer simply uses that "not  
null" type  as a base?  The goal being to use the "minLength"  
qualifier only once.

Any help would be appreciated!

thanks,
-lev
