XML Schema documents can be edited in Text View, Grid View, and Schema View. The default view in which XML Schema documents open can be set in the File Types section of the Options dialog. You can switch between views while you edit, using the view that is most useful for the current purpose. XML Schema documents are typically saved with the extension .xsd or .xs.
Editing in Text View
In Text View an XML Schema is edited as an XML document; the editing features available for XML documents are also available for XML Schemas. As with all XML documents where the schema is identified and accessible, Text View entry helpers display the items available for addition at the cursor location point.
Editing in Grid View
In Grid View an XML Schema is edited as an XML document; the editing features available for XML documents are also available for XML Schemas. When an item in Grid View is selected, Grid View entry helpers display the items available for addition at the cursor location point.
Editing in Schema View
Schema View is a graphical interface for designing schemas. While you create/edit the schema in Schema View, XMLSpy generates a corresponding text document behind the interface. How to create and edit XML Schema documents in Schema View is described in detail in the section Editing Views | Schema View.
