Well, If you are free to change the XML structure at any time - where's the=

point in wondering if an element is a parameter, a CDATA or an element? You=
=20
can change everything to element and CDATA and that's all. If you have a=20
fixed XML structure, that's not supposed to change, having a DTD is=20
obligatory in orther to maintain consistency of the format.=20
So, you can either work without using getType (since you define the XML=20
structure yourself), or use a more complex API that will serve you well.
