There are two things here: 1) The XML specification defines a serialization syntax. It does not define what that syntax models. Thus, in a strict sense, my comment is correct. However, depending on your view of the world, this may or may not apply. 2) For many (most?) people, you are correct -- the native XML database models the data in the documents. In this case, the model of the document is a proxy for the objects used to model the data, just like tables and columns are a proxy for the objects in the relational model. A better wording is therefore: "A native XML database defines a set of objects that model an XML document and uses these objects to model the data in that document. The minimal model is elements, attributes, text, document order, and hierarchical order." Other definitions welcomed. I've been wrestling with this one for about six months... -- Ron
