That's the easy part :=) (meaning no offense) What's difficult is to extend it without having to predict what the needs will be (and where the document will have to be extended) and that's unfortunately the real challenge for real life open world applications. <snippet-from-another-answer> Let's take a simple example... I have a text only element: <ns1:foo>This is a simple example.</ns1:foo> If I extend this example to include a semantic element to identify "simple" as an adjective: <ns1:foo>This is a <ns2:adj>simple</ns2:adj> example.</ns1:foo> I am changing a text leaf node into a mixed content including 2 text nodes separated by a child element and this will likely break 90+% of the existing applications. The situation is probably better if you want to add an element in an elements only content model, but even in this case, if you take real life applications, how many of them will you break? 30%, 50%, 75% ? Way too many in any case! </snippet-from-another-answer> Eric -- See you in Seattle. http://knowledgetechnologies.net/ ------------------------------------------------------------------------ Eric van der Vlist http://xmlfr.org http://dyomedea.com http://xsltunit.org http://4xt.org http://examplotron.org ------------------------------------------------------------------------
