What the use of writing flexible schemas if the applications are not also flexible and open to accept the same range of documents than those flexible schemas? At the end of the day, it's probably even more than a matter of writing flexible applications, it's a different perspective on what's a XML document. There are applications for which a XML document is a transient stream used as a closed exchange between two points for which it's OK to use closed schemas. Beyong flexible schemas and flexible applicarions, what we need is *flexible thinking* and my strong feeling is that all the other applications should look at XML documents as sources of information open and imprevisible in which they fetch what they need and leave what they don't need right now for potential later use... This leads to accept and publish more information in XML documents than you need it short term and it's probably the most fundamental difference between being application and document oriented (more fundamental than discussing over the legitimity of mixed contents)!
