The first application using Oracle as underlying dbms

We are about ot publish our first bibliographic database on the web using Oracle. At this moment the ISRIC world soil information database, is still relying on the underlying Minisis database. The database used to be prepared offline and published using WebQuery. ISRIC wants to add and modify records via the web interface. Since this is a relatively simple application we decided it would be our first Oracle based application. Modifying records works fine. Now we are implementing xsd validation and ran into problems using the libxml libraries. We needed to implement the newest version and these are stricter. So we ran into problems with silly xslt mistakes which did not create any problems before. We have been debugging and everything is working again.
