Attributes

An element of the complex type can have attributes.

A simple element can contain only its value.

XSD Attribute Example:

<xs:attribute name="power" type="xs:integer"/>

The following is an element with the attribute declared in the above example.

<hero power='1000'/>

Required Attribute

A required attribute must appear in the element containing it.
