XML Schema(XSD): Is it possible to create a rule/relation for an element based on another element?

I have 2 elements:

1. Total number of connections


2. Connections per second.

I would like to enforce the following rules:

• Connections per second should be less than or equal to total connections.


• Default value of connections per second should be equal to total connections

Currently I have total connections as following:

<xs:simpleType name="TotalConnections" use="optional" default=1> 
    <xs:restriction base="xs:positiveInteger"> 
        <xs:minExclusive value="0" />
         <xs:maxInclusive value="8000"/> 
    </xs:restriction> 
</xs:simpleType> 

How do I link total connections with cps in my schema?
