The description element in the returned RSS xml can be formatted by setting the URL
parameter sysparm_format=true and specifying the format string in the
property glide.rss.description_format.
By default, when the URL parameter is present, the description element will be formatted to
contain the field label and value using the following format
string:
<b>{1}</b>: {2}<br/>
{0} - field name
{1} - field label
{2} - field value
This default format string can be overridden using the property
glide.rss.description_format. An example of the formatted RSS feed can be
seen in the following screen capture from Firefox:그림 1. RSS Format
