Global declarations are declarations that appear as direct children of the <schema> element.
Global element declarations can be reused throughout the XML Schema.
Local declarations do not have the <schema> element.
Local types can be used only in their specific context.
Referring to an Existing Global Element
To refer to a global element declaration, include a ref attribute and specify the name of the global element as the value.
<element ref="target:first"/>
