In this case, "universal" means that the words "ersatz" and "publications" have to appear in every publisher of a given book. If a book has more than one publisher, all of them should contain the words "ersatz" and "publications". This is not the usual semantics in XPath in which an "existential semantics" is assumed. that is, if a condition is satisfied by one istance of an element, the query returns true. The "universal semantics" makes sense in the context of the above use case.
