Incidentally, I have the book and Buneman's semistructured data article. Their models for semistructured data bring up another question. Do you happen to know if this model has changed - or if there are just several ways of expressing the same model. The mismatch is illustrated by the figure in the article, and the figure on page 33 in the book, basically the leaves of the tree in the book have value, whereas they are "void" in the article, but have a label of a "type" (rather than a symbol I assume)
