Either > lose both or keep both, say I. First: Well, I am perfectly happy to lose ENTITY/ENTITIES and while we're at it ID/IDREF. URLs and XPointers can do both jobs better. Let's keep our layers clean and separate! Second: Even so, I don't follow your argument. The schema needs to validate that there is a unparsed entity with a particular name. Why does the declaration have to be done in the schema? It makes perfect sense to me that a *document* should declare what external resources it needs (through a URL or entity declaration) and that the *schema* would verify that an element that is supposed to reference a resource actually does (whether through a URL or entity). Your argument seems analgous to arguing that IDs should indirect through an "ID object" in the schema. Entities and IDs are a type of object that are tied to a document. Constraints on them apply to a class of documents. The former should go in a document and the latter in a schema. -- Paul Prescod - ISOGEN Consulting Engineer speaking for only himself http://itrc.uwaterloo.ca/~papresco And so, in one of history's little ironies, the global triumph of bad software in the age of the PC was reversed by a surprising combination of forces: the social transformation initiated by the network, a long-discarded European theory of political economy, and a small band of programmers throughout the world mobilized by a single simple idea. - http://old.law.columbia.edu/my_pubs/anarchism.html
