    Until we have an EPUB sans XHTML,
      it’s worth considering a lightweight subset of the format, one
      that represents a convention over configuration approach. A
      “microformat” version — EPUB: the beach novel edition — could be
      mechanically “upsampled” into big boy EPUB for use in the real
      ecosystem. It won’t solve the problem of heterogeneity in books
      (which is, after all, not actually a problem except to reading
      system developers), but it could make it easier for even
      experienced ebook authors to create publications without firing up
      an XML editor, for the majority of books that have very simple
      metadata requirements.  I’ll outline some ideas for that in a
      future post."
