Question 1:
============================================
30 points

In this exam you get two class dictionaries:
The first one is called SchemaSimple and the the second
one SchemaComplex. SchemaSimple is a simplification
of SchemaComplex. You find the structure of SchemaSimple
also in SchemaComplex. SchemaSimple is given 
in graphical form as a UML class diagram and the
ComplexSchema is given in textual form.

SimpleSchema will be used for traversal related questions
and ComplexSchema for programming questions.
The class dictionaries are about XML schemas. The cds define
the structure and the syntax of XML schemas but
you don't need any previous knowledge of XML.
Both cds only define a subset of XML schemas.

Consider class dictionary SchemaSimple and 
the traversal strategies:

from Schema to TypeDef : 10 points
from Schema to Attribute: 10 points
from Schema to Element : 10 points

Highlight all the classes whose objects might be 
traversed on some object of the start class of the strategy. 
Mark the classes directly in the UML class diagram
(you get 3 copies of the diagram).

Example
The traversal strategy: "from Attribute to AttrValue" results
in two classes: Attribute and AttrValue.
