When you import an XML schema, the Designer creates an XML definition that represents the entire schema. If you import an XML file with an associated schema, you can create XML views for just the elements and attributes in the XML file instead of all the components in the schema. The Designer creates a definition that is limited to the components in the XML file.
To import part of a schema, import an XML file that references the schema. Select the option to create XML views only for the elements and attributes in the XML file.
