DB Publishers to XSLT epub output -- POETRY TAG strangeness

I have started to investigate the Docbook for Publishers and using the latest Docbook XSLT to render it. I'm primarily interested in producing epub output. 

I'm using sample code from the Docbook for Publishers Guide and am using the docbook-xsl-ns-1.79.1/epub3/chunk.xsl to transform everything: 

I think this is a bug. Let me know if you want me to file a bug or if this is a known issue.

The output is very strange. (I don't know if the HTML source  will appear in the email, so I'm putting it at this URL: 

http://imaginaryplanet.net/private/test2.xhtml

The problem is that the POETRY tag is showing and you have special characters to simulate the < and >. (So the output should have been <poetry>  and </poetry> which won't be rendered in the HTML output?
