What are your thoughts on this? /Roger Say I want to compare the elevation to the minimum allowed by FAA regs for that location. The regs probably contain it as a string somewhere. Now I have to do some completely different steps to make the comparison, somethng unforeseen when both the schema and the regulation were created. The number in my document and the number in the reg live on in some form, destined to be reused in many ways. On the other hand, with many of these strong-typing-desiring applications, the data probably will not live on. It is ephemeral, designed for one short transaction and never to be seen again. So the objection would perhaps have the least effect in these cases. Nevertheless, I want to be able to get hold of the original contents in those elements, even if I can also get their data types.
