See sample URL. Should be able to localise this.
Oops, missed that. I wonder if it's even necessary to have "Marked as" at all; I just used that text to match the mockup. index vs. noindex should be clear enough (and I suppose there's no need to localize it, as it's displaying what would be used in a meta tag).
There is no need to expose technical stuff like that if the user only needs to know whether the page can be indexed by search engines or not.
So perhaps messages pageinfo-robots-index and pageinfo-robots-noindex then?
