For instance - Sablotron can accept a struct with callbacks as it's input document, through it's SXP interface. As far as your previous mail - I don't see how you can seperate the two: 1 unified XML extension and a core that introduces XML functionality natively. It seems to me, that you have to agree on the core bit first and work on both the core and extension together, to see what is required from the core. -- With kind regards, Melvyn Sopacua <?php include("not_reflecting_employers_views.txt"); ?>
