Even for compound documents, extension by the NVDL method seems even scarier than the ANY element - at least you know where ANY is going to show up. In the context of developing a schema for the exchange of trademark registration data among WIPO and states party to the Madrid Agreement, OHIM put ANY in the base schema with the intention that it be replaced by those additional elements required by each national office for their internal processing not already provided for in the base set. Other offices would, in general, ignore those easily-identified elements. As elegant as NVDL appears to be, the unpredictability it introduces is not just in machine processing, but in business processing as well. Industrial property offices don't usually want to see data in a submission that is not supported by some business rule. Extraneous data can create considerable confusion and potential liabilities. Somewhere, somehow, the overall business process has to be controlled in order to reduce it to machine-based processing, that it, it has to be minimally predictable, or the business won't invest in automating it. It's fairly easy to show customers how an XML schema makes their business objects amenable to machine processing. I don't think I'll be introducing NVDL to them any time soon. We currently publish 10,000 patent documents each week based on a DTD with an external table DTD and MathML and expect to introduce some others. So far, we haven't needed NVDL.
