SceneGraph Sample Feed Doesn't Validate

I’m moving from DP and have found that my feed, while working in DP for 4+ years, is not set up quite right. I’m trying to build a proper feed, but ROKU’s own SceneGraph sample feed doesn’t validate. Are there any good samples that I can work from?

Getting same think. Sample gives these two errors.
