The information required to >interpret digests, therefore, must be a top-level element. All digests in any >given manifest must use the same digest algorithm. Is this possibly overly constraining? For very resource-constrained devices, it is reasonable to expect the device to only have a single digest algorithm available in it. Would we want another digest algorithm available to allow higher-processing systems to perhaps use a stronger check. I think if we want require a single digest format per manifest, there should at least be motivating text for doing it this way, as well as why there is only a single digest allowed per entity. David
