Defining an XML model

Model Items page

The Items page of the model property sheet displays the list of global objects (with no parent symbol in the diagram, directly linked to the <schema> tag) created in the model. This list reflects the order in which global objects are being declared in the schema. If you want to change this order of declaration, you must select an item in the list and use the arrowed buttons, at the bottom- left corner of the page, to move the selected item in the list:

Button	Moves item
	Top of the list
	Up one page
	Up one line
	Down one line
	Down one page
	Bottom of the list

You can also use the Items page to create global objects in the model:

Tool	Tooltip	Description
	Add Element	Adds an element to the model
	Add Group	Adds a group of elements to the model
	Add Attribute	Adds an attribute to the model
	Add Attribute Group	Adds a group of attributes to the model
	Add Simple Type	Adds a simple type to the model. Only
		available in a model targeted with XSD
	Add Complex Type	Adds a complex type to the model. Only
		available in a model targeted with XSD
	Add Notation	Adds a notation to the model, to describe the
		format of non-XML data
