Here's my implementation for this:

class FeedItem:
Add:
/**
* Creative commons license
*/
var $createCommonsLicense;

class RSSCreator091:
Change function createFeed:
function createFeed() {
$feed = "<?xml version=\"1.0\" encoding=\"".$this->encoding."\"?>\n";
$feed.= $this->_createGeneratorComment();
$feed.= $this->_createStylesheetReferences();
$feed.= "<rss version=\"".$this->RSSVersion."\"\n";
if ($this->createCommonsLicense != '') {
$feed .= " xmlns:creativeCommons=\"http://backend.userland.com/creativeCommonsRssModule\"\n";
}
if ((is_array($this->namespace)) && (count($this->namespace > 0))) {
foreach($this->namespace as $index => $value) {
$feed.= " xmlns:".$value."\n";
}
}
$feed.= ">\n";
$feed.= " <channel>\n";
$feed.= " <title>".FeedCreator::iTrunc(htmlspecialchars($this->title),100)."</title>\n";
$this->descriptionTruncSize = 500;
$feed.= " <description>".$this->getDescription()."</description>\n";
$feed.= " <link>".$this->link."</link>\n";
$now = new FeedDate();
$feed.= " <lastBuildDate>".htmlspecialchars($now->rfc822())."</lastBuildDate>\n";
$feed.= " <generator>". $this->version()."</generator>\n";
if ($this->createCommonsLicense != '') {
$feed.= " <creativeCommons:license>" . $this->createCommonsLicense . "</creativeCommons:license>\n";
}
