Defining complexTypes That Contain Only Attributes
An XML Schema allows you to create groups of attributes. This makes it easy to create a complexType that contains only attributes. The first step is to create an attributeGroup. You can then create a complexType and add a reference to the attributeGroup to the complexType.
