It displays a tree of what the XML document you are modelling should look like. And this tree is completely editable. Add an element, and a new simpleType is created.

• Integrated Development Environment (IDE)
  In addition to xmlDraft's unique ability to display to the user the XML Document that the schema is defining, xmlDraft is a complete IDE for xml schema creation and modifications.
