The closer you get - eg, the fewer competing standards there then are - the easier writing applications that understand the smaller number of possibilities gets; and thus the chance of a reader not understanding a given writer lessens, and the more time the developers have to do better things than handle yet another import format. Perhaps there ought to be a way of finding 'import filters'. Say an application reads documents using a type defined in namespace A. Perhaps it finds a document whose root element is in namespace B. Maybe it should try looking for RDDL accessibly by GETting the namespace URL of B, and look up in there to find some XSLT to translate an instance of the element into an instance of the desired element in namespace A... Then the designer of SuperPersonML (with added breath-freshening ingredients) could write some XSLT to convert a SuperPersonML instance into LimitedButWidelyUnderstoodPersonML and hook it up. Perhaps the maintainers of a namespace ought to be able to publish converts *into* that format in their RDDL, as well. Or something like that. ABS
