-- When you import an XSD file in Mapping Services it is impossible to change the prefix of the namespace. By default it was p1 or p2 for exemple.

* Since Mapping Services 2.4 SP7P1 it now possible to edit the namespace prefix.

If you are doing a new import, change the prefix right after because after doing the map you will have to change all the p1 or p2 by your values in the map with the "text editor".
