Event though we had referred to the type:

<xs:element name="student" type="my:person"/>
<xs:element name="parent" type="my:person"/>

The elements don't use the type's name:

<my:student>
<name>Jimmy Smith</name>
<age>2</age>
</my:student>

<my:parent>
<name>Jane Smith</name>
<age>33</age>
</my:parent>
