Separate permissions for global and per-node configuration

I think there should be separate permissions for accessing site-wide XML sitemap settings—which only highly-privileged users should touch, I would think—and changing an individual node's settings from its node edit page—which content editors commonly need to do. Just because someone needs to be able to change the inclusion settings for their own nodes doesn't mean they should be able to add a new sitemap, update cached files, or change search engine submission settings. "Administer XML sitemap settings" seems like appropriate language for the site-wide configuration. I would add something like "Edit node inclusion settings".
