    It says both extensionWrap *and* extensionEmbedded are required subelements within pbcoreExtension (and instantiationExtension) yet none of the examples demonstrate how both are used together within the parent element. Could this be corrected or explained?

    What the present examples *do* demonstrate is that, perhaps, extensionWrap is best for incorporating a few non-PBCore elements, while extensionEmbedded is best for handling bulk quantities.

    But if both are required, then it would just be a repetition of information, just structured slightly differently, which seems unnecessary. But I could be misunderstanding how these elements are used…
