The type tree generated from a schema document allows for namespace
declarations to appear in the global elements’ open tags as well as in global types.
Global elements can also contain schemaLocation or
noNamespaceSchemaLocation attribute from the XML Schema Instance
namespace:
xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”
Also, for the elements that were declared nillable in the schema document, the nil
attribute can be used in the instance document. This attribute also belongs to the
XML Schema Instance namespace.
NonDocData Item
The NonDocData item is partitioned and represents the non-document data that
can be contained in the XML instance document. The NonDocData item contains
three subtypes, PI, Comment, and CDATA which can be viewed when the tree is
expanded:
The PI text item represents an XML processing instruction, the Comment text
item represents an XML comment, and the CDATA text item represents a CDATA
section. The NonDocData item is used as a floating component when a
processing instruction, comment, or CDATA section appears in the instance
document.
Prolog Category
The Prolog category contains the type tree constructs used to describe the XML
prolog in the instance document.
