<p>A schema is functionally equivalent to a DTD, but is written in XML. A
schema also provides extended functionality such as data typing, inheritance,
and presentation rules.</p>
<p>For more information on XML schema, see the following:</p>
<ul>
<li> <xref format="html" href="http://www.w3.org/TR/xmlschema-0/" scope="external">http://www.w3.org/TR/xmlschema-0/</xref> </li>
<li> <xref format="html" href="http://www.w3.org/TR/xmlschema-1/" scope="external">http://www.w3.org/TR/xmlschema-1/</xref> </li>
<li> <xref format="html" href="http://www.w3.org/TR/xmlschema-2/" scope="external">http://www.w3.org/TR/xmlschema-2/</xref> </li>
</ul>
