Multiple Links with Asterisks?

I'm working on parsing some RSS 2.0 content, and I've found that several popular RSS 2.0 documents have multiple links embedded in one <link> tag separated by asterisks.

For instance, this is from the Yahoo Finance feed:

<link>http://us.rd.yahoo.com/finance/news/rss/story/*http://us.rd.yahoo.com/finance/news/topnews/*http://biz.yahoo.com/ap/091009/as_india_earns_infosys.html</link>

Is this part of the RSS 2.0 spec?  It doesn't look like it to me.  Is this common?  How should I handle this?

Thanks,
-Nate
