Custom views are groups that you create with the XML Wizard or the XML Editor. If you use the XML Wizard to create custom views, the wizard creates views containing all the components in the schema. If you use the XML Editor, you can define each view and choose the components.
The elements in the views and the relationship between views are dependent on the schema the Designer creates in the repository when you import the definition. The XML Editor validates XML definitions using the rules for valid views.
