In designing complex systems it is a good idea to re-use well-tested components where possible. If, for example, your power station relies on mathematics, physics, chemistry, safety protocols, etc. then it will make sense to re-use those developed in a community-wide fashion. In an XML document it is straightforward to detect the namespaces used and to separate the components. I find it much easier to extract the separate information components from an XML file than (say) an RTF document. I don't usually contribute to general discussions on XML-DEV but I'd like to urge members to think in terms of re-usable components wherever possible. To what extent we can develop them here I don't know, but IMO it represents a major advance over the proprietary approach. XML documents are open in a way that many others aren't and are often much easier to dissect than objects and relational data. P.
