Sure - I think a concrete example would better illustrate my point. Several years ago I worked on the prototype of a US Environmental Protection Agency initative called "Central Data Exchange (CDX[1])". CDX is the point of entry (a central hub) for environmental data submissions to EPA from entities such as governemnt agencies, states, localities, tribes, and laboratories. The submissions would be along the lines of water testing results, factory emmissions, etc. In this context,one may classify this XML information as "data-oriented"/"exchange-oriented", rather than "document-oriented"/"record-oriented". However, because of various regulations, EPA was required to archive the submissions not only as they were received - but in every stage of their life cycle (i.e. whatever processing was applied to the data, such as conversion from XML to flat-file format). These archives - a.k.a "records" - were required to be retained for certain number of years (I *believe* 25 years), for multiple reasons among which was to allow them to be used as evidence in litigation if necessary. So in summary, this "data-oriented"/"exchange-oriented" XML was also considered to be "record-oriented".
