Hello chethan,
I have been making some tests, and didnt get it to work, it a good idea but, if you get into this, remember, that there is only one "projectName" in the xml definition, and all tables will get this value as namespace (see service builder).
Let us know if you get some results.
Saludos, Jack.
Pd. : I tried by making files with one application definition each, and in the main xml, putting some sintax like this:
1<!DOCTYPE page [
2<!ENTITY classrooms SYSTEM "SchoolCourse_Classrooms.xml">
3]>
and this where the application is supposed to go:
1&classrooms;
