Is the Cosmological Principle still valid?

Given that astronomers appear to be discovering structure in the Universe at greater dimensions, is it possible that the Cosmological Principle is no longer fully valid as an assumption when studying the "life" of the Universe? Discuss.

Ok I've discussed that. Now what?
Why would finding the universe has structure affect the Cosmological Principle ?
The Cosmological Principle is if anything enhanced by discovery of structure, as presumably such structure could be observed from anywhere.
Question Author
If the universe has structure at greater and greater size then this would mean that it may not be isotropic, one of the assumptions made by the Cosmological Principle.
Not an area I've studied in detail but I don't believe one needs to have an unchanging properties in all directions in order to not be in a privileged position. Maybe no matter which point you observe from, such changes seem apparent. And besides wouldn't apparent structure suggest large scale lack of change anyway ?
Sorry, but this seems a confused post to me. What greater dimensions are you talking about? What structures? How do you think that this effects the cosmological principle?

I have heard no reported sightings or observations from reputable astronomers that in any way threaten homogeneity or isotropy. Please elaborate on your original point, or better still provide a link.........
