As an optional attribute whose value can only be the empty string or
the same as the attribute's name?
Something like:
<xs:attribute name="checked">
<xs:simpleType>
<xs:restriction base="xs:string">
<whiteSpace value="collapse" />
<xs:enumeration value="" />
<xs:enumeration value="checked" />
</xs:restriction>
</xs:simpleType>
</xs:attribute>
But there are things that are waaaay more difficult to implement in
XML Schema (and I believe some are just impossible to represent in XML
Schema)
