A schema is an XML-written text defining the content and structure of an XML document. An XML model is a graphic representation of a schema.

You can use the following tools to reuse in your model global objects from other schemas:

Tool	Tooltip	Description
	Add Include	Adds a specified schema file to be included in the target namespace of the current schema
	Add Import	Adds a specified namespace whose schema components are referenced by the current schema
	Add Redefine	Adds a specified schema file whose simple and complex types, groups and attribute groups can be redefined in the current schema
	Add Annotation	Adds an annotation to the model to provide documentation or application information
