We have a massive site that is having some issue being fully crawled due to some of our site architecture and linking.

Is it possible to have a XML sitemap index point to other sitemap indexes rather than standalone XML sitemaps?

Has anyone done this successfully? Based upon the description here:

http://sitemaps.org/protocol.php#index it seems like it should be possible.

Thanks in advance for your help!
