Google WMT shows sitemap.xml highest ranked for one main keyword

[nux]

Hello, I am seeing my sitemap.xml show up in Google webmaster tools at the top for one of the main keywords for my site.  This is in the Your Site on the Web - Keywords section.  The URLs of my site contain this keyword, which is why I figure it showed up.

I'm curious if this should be a concern to me?  I find it odd that the sitemap would show up in this way.

Thanks

Do you know if it's actually ranking? If it is, make sure that your sitemap has the proper header which identifies it as an xml sitemap. You obviously want Google to crawl it, but if you don't have the proper header, it will treat it like any other page and you might rank for it. You can also put a "noindex, follow" directive on your sitemap, which will crawl it, but not index it as a SERP.
