I don't see how this would solve the problems. To be honest, I don't see a difference. A delivery unit (as it seems to be the understanding of the DI WG) is a collection of resources with one "primary" resource and 0 or more "additional" resources, that are fetched by a user agent after fetching the primary resource without activation by the user (in XLink terms: xlink:actuate="onLoad"). Don't you define the "Web Unit" to be exactly this? -- Johannes Koch Spem in alium nunquam habui praeter in te, Deus Israel. (Thomas Tallis, 40-part motet)
