XmlSchemaAttribute Class
Assembly: System.Xml (in system.xml.dll)
Attribute declarations can be present as child elements of the schema element (having global scope) or within complex type definitions. For complex types, attribute declarations can be present as local declarations or references to attributes with global scope. Both global and local attribute declarations have the optional type attribute that refers to an existing simple type. If the optional type attribute is not used, the attribute declaration (global or local) must define a local simple type.
The following example creates the attribute element.
