http-serializer requires xsi:type

I attempted to move a pipeline from the
legacy xml-serializer to the http-serializer.
However, I get an exception, "Root element must
contain an xsi:type attribute" Not sure why this
is happening, never a problem before with a
myriad of namespaces.

Any directions welcome, thanks.

Yes, the HTTP Serializer accepts two different types of documents only:
binary an text, as per this:

http://www.orbeon.com/ops/doc/processors-serializers-http

You do need an xsi:type attribute on the root element, and the content
is either text or binary encoded as Base64.

If you want to no longer use the XML serializer, you have to use, in
addition to the HTTP serializer, the XML converter, for example (from
epilogue-servlet.xpl):

<p:processor name="oxf:xml-converter">
<p:input name="config">
<config>
<encoding>utf-8</encoding>
</config>
</p:input>
<p:input name="data" href="#xformed-data"/>
<p:output name="data" id="converted"/>
</p:processor>
<p:processor name="oxf:http-serializer">
<p:input name="config">
<config>
<header>
<name>Cache-Control</name>
<value>post-check=0, pre-check=0</value>
</header>
<content-type>application/xml</content-type>
</config>
</p:input>
<p:input name="data" href="#converted"/>
</p:processor>
