+<h3>Type Conventions</h3>
+<p>The PROV-DM states that type information is described using a the prov:type PROV attribute with and may occur multiple times for a given entity, activity, agent, or relation.</p>
+<p>PROV-XML uses the element <code>prov:type</code> to represent the prov:type PROV attribute.  This element can be use to represent both PROV and non-PROV type information.  The following examples shows type information encoded using the <code>prov:type</code> element.</p>
+<pre class="example" title="type information using prov:type PROV attribute" ignore>
+&lt;prov:document
+    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
+    xmlns:prov="http://www.w3.org/ns/prov#"
+    xmlns:ex="http://example.com/ns/ex#"
+    xmlns:tr="http://example.com/ns/tr#"&gt;
 
-<div class="note">
-<p>REVIEW QUESTION:</p>
+  &lt;prov:entity prov:id="tr:WD-prov-dm-20111215"&gt;
+    &lt;prov:type xsi:type="xsd:QName"&gt;prov:Plan&lt;/prov:type&gt;
+    &lt;prov:type xsi:type="xsd:QName"&gt;ex:Workflow&lt;/prov:type&gt;
+  &lt;/prov:entity&gt;
 
-<p>The current design has mirrored the naming from PROV-N.  This often
-involves reliance on the "prov:type" attribute to distinguish some
-relations.  In order to simplify the overall expression of those
-concepts in XML, we are considering adding additional explicitly named
-top level elements rather than requiring "prov:type".
-</p>
+&lt;/prov:document&gt;
+</pre>
+<p>PROV-XML defines complexTypes to match the PROV defined type values.  These types provide a more native XML representation of PROV types.  The following example is considered equivalent to the previous example because the element <code>prov:plan</code> has type <code>prov:Plan</code>.</p>
+<pre class="example" title="type information using schema defined types" ignore>
+&lt;prov:document
+    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+    xmlns:xsd="http://www.w3.org/2001/XMLSchema"
+    xmlns:prov="http://www.w3.org/ns/prov#"
+    xmlns:ex="http://example.com/ns/ex#"
+    xmlns:tr="http://example.com/ns/tr#"&gt;
 
-<p>For example, a Quotation is currently expressed in PROV-N as a type
-of Derivation like this:</p>
-<pre class="codeexample">
-wasDerivedFrom(a, b, [prov:type='prov:Quotation'])
+  &lt;prov:plan prov:id="tr:WD-prov-dm-20111215"&gt;
+    &lt;prov:type xsi:type="xsd:QName"&gt;ex:Workflow&lt;/prov:type&gt;
+  &lt;/prov:plan&gt;
+
+&lt;/prov:document&gt;
+</pre>
+<p>Because the <code>prov:Plan</code> complexType is defined as an extension of the complexType <code>prov:Entity</code>, the following example using <code>xsi:type</code> is valid and considered equivalent to the two previous examples. The attribute <code>xsi:type</code> tells an XML parser the complexType of the element.  The value of <code>xsi:type</code> must be a complexType derived from the default element type.</p>
+<pre class="example" title="type information using xsi:type" ignore>
