<!--
Your suggestion:
<xs:assert test="empty(../Entity2)"/>
but for my case may be it will be
<xs:assert test="empty(../@name)"/>
as entity name is not fixed. I have tried both the way but it is not working.

-----Edit 3-------
I have four types of node: 1. Entity, 2. MultiAspect, 3. Aspect and 4. Specialization. If the node is Entity then its successors are Aspect, MultiAspect or Specialization. If the type of a node is Aspect, MultiAspect or Specialization, then the type of its children are Entity. The root node is always Entity.
I have designed my XML Schema using the above rules. I have used "assert" to validate the XML file. I have used
every $x in .//* satisfies empty($x//*[node-name(.) = node-name($x)])
and also tried using entity instead of *
every $x in .//entity satisfies empty($x//entity[node-name(.) = node- name($x)])
But it is showing error all the time. XML Schema is given above.
