Exception when running WFS-T transaction from OGC spec

I cut and pasted the insert transaction example from section 12.2.4 of the WFS 1.1 spec (OGC 04-094). There were two locations that had ellipses that I removed (<gml:posList>-99.99 22.22 ...</gml:posList>). I got the same result whether I left them in or not: the query does not return, and the geoserver log shows an exception:

53012 [btpool0-5] INFO /geoserver - Loading WebApplicationContext for Spring FrameworkServlet 'dispatcher'
org.eclipse.emf.ecore.resource.Resource$IOWrappedException: The reference to entity "domainname" must end with the ';' delimiter.

I've attached the xml query and the full traceback.
