Actually, the appropriate editorial work is to recast the description of caching to talk about external behavior rather than internal behavior. What a cache stores or doesn't store is internal behavior. In a couple of cases (copyrighted or authenticated material) we actually care what a cache does or doesn't store. However, in this case, the only thing we care about is that the cache not return partial data as if it were complete data. We're should reserve "MUST" and "MUST NOT" for things that are requirements of the protocol. Larry
