Are symlinks recognized by iCloud?

I would love to keep all of my personal files (docs, photos, videos, music) in my user folder where they're supposed to be, and still have them on iCloud for my mobile devices. I thought of putting symlinks that point to the user folders in the iCloud folder in ~/Library/Mobile Documents. Does anyone have authoritative information to tell if these symlink targets will be synced with iCloud similar to the way symlinks can be used with Dropbox? Thanks.
