I am trying to query the content in a Set.  
I want to know if the Set contains only   
Poly, Vertex, Face, Edge, UV, etc.  
Is it possible to do it in MEL??

This is what I have tried:

// Get a list of all Sets.  
string $allSets[] = `ls -sets`;

for( $possibleSet in $allSets )  
{  
// Is this a Quick Set??  
 if (`nodeType UVSet` == "objectSet")  
 {  
 // This is a Set.... But how do I   
 // find out if it has the following:  
 // Poly,Vertex,Face,Edge,UV...etc  
 ...  
 }  
}

My purpose is to write (yet another) Set manager,  
but mainly to assist myself in Poly modelling.

(This is the first time I'm looking into MEL)
