item description element not indexed

The RSS feed's item description is not written to any field in the Solr index.

I have a typical RSS feed with the general structure:

<rss>
<channel>
<title></title>
<link></link>
<description></description>
<item>
<title></title>
<link></link>
<pubDate></pubDate>
<description> *** the description I do want *** </description>
<author></author>
<category></category>
</item>
</channel>
</rss>

Example:
For the RSS feed: http://www.onemansjazz.ca/component/option,com_rss/feed,RSS2.0/no_html,1/
the rss/channel/item/description field is not indexed into Solr.
Example notes:

• what does get written to the Solr "description" field is the description metadata from the website, i.e. "Jazz radio show from Winnipeg on CKUW 95.9 FM, hosted by Maurice Hogue." in this case.
• on the "Dechromed Content" tab of the job, "No dechromed content" is selected. I'm not sure if that is relevant.
