Do we really want to describe 'phys' hundreds of times? No. The question I ask on the descriptions is could it be generated instead. Rob

No. The > question I ask on the descriptions is could it be generated instead. I agree. If the description had mentioned why particular PHY was referenced, I would have kept that, but "the phy is a phy" is probably not something we want to duplicate everywhere.

No. Agree, for common properties we as a minimum want a phy-common.yaml or some such - and have the description exactly once. > The > question I ask on the descriptions is could it be generated instead. That could also be an idea, but assuming most people look at the source then the same "most people" would miss the generated descriptions. But to be clear - I see that phys: is a commonly used property so no problem to have the description dropped here. Ack still stands. Sam

'maxItems' equal to the 'items' list length is redundant. 'maxItems' is preferred for a single entry while greater than 1 should have an 'items' list.
