recognize this type of error. 
Address type does not define any attributes on its own. This is why the Attr 
category does not contain any subcomponents. 
Element Category 
The Element category contains constructs that represent the global elements 
from the schema. The example schema has only one global element - Person, 
which is why the Element category has only one child node – the Person 
category, as shown in the following: 
The Attr subcategory of Person represents the placeholder for the Person 
element attributes. Since the Person element’s type has only one attribute, Title, 
only the Title item is present. 
The AttrList unordered group contains the attributes of the Person element. 
Apart from the Title attribute, this group also contains the placeholders for 
namespace declarations, noNamespaceSchemaLocation and nil attributes.
