 That requirement doesn't make sense AFAICT: 1. As you say, the customer has the DTD. Why do they want to invoke a network process to a web machine to validate a local document? That is not only more work, it is error-prone and opens up a security hole if you do something untoward. 2. Now they have to negotiate with you anytime they want to change their own DTD. They are as Bill Gates puts it so well, 'outsourcing their brains'. 3. Why are they validating an RPC command? I understand a requirement that you validate before sending but not one where they validate against their DTD copied to your machine. Without understanding the basis for the requirement, it's hard to say if the best design pattern is to give them what they want or to chide them into a more sensible solution. They don't seem to understand why DTDs were made optional in XML. len -----Original Message----- From: john Mani [mailto:john@s...] We have an application that exchanges XML with a customer's application, running at their site. The XML DTD is specified by the customer. These XMLs are used more as a RPC type command, rather than as documents that may be archived and reused later. The customer's XML processor demands that the XML documents we send have a <DOCTYPE .. > declaration, that points to a URL hosted by us. I would prefer that I do NOT include any <DOCTYPE > declarations, but just have the XML's be declared 'Standalone'. The receiver's parser afterall has the DTD to insure the validity of the document. And it certainly doesn't make much sense for me to be hosting the DTD URL, rather than the DTD owner (me customer, in this case). Anyways, what's a design pattern in such situations ?
