Question 3:
===========
18 UNKNOWNs

Use again class dictionary SchemaComplex.
Consider the following two program fragments.
The first one eliminates all AttrValue-objects contained
in the attrs data member of Element-objects.

For example:

<xsd:element name="purchaseOrder" type="PurchaseOrderType"/>  
is translated to:
<xsd:element/>  

The second program fragment eliminates name space references 
(NSRef-objects)
from complex types (ComplexType-objects). For example:

<xsd:complexType name="PurchaseOrderType">     
is translated to:
<complexType name="PurchaseOrderType">

Find the UNKNOWNs below (cg2 is the class graph for XML schemas):

    System.out.println(" Eliminate attributes from elements ");
    cg2.UNKNOWN1(s,"from UNKNOWN2 to UNKNOWN3", UNKNOWN4 UNKNOWN5() {
      void UNKNOWN6(UNKNOWN7 host){
	System.out.println(" Element found ");
	host.UNKNOWN8(new UNKNOWN9());
      }
    });
    System.out.println("========");
    System.out.println(" Eliminate name space refs from complex types ");
    cg2.UNKNOWN10(s,"from UNKNOWN11 to UNKNOWN12", UNKNOWN13 UNKNOWN14() {
      void UNKNOWN15(UNKNOWN16 host){
	System.out.println(" ComplexType found ");
	host.UNKNOWN17(UNKNOWN18);
      }
    });
