Just to say thank you for this article. I have just started learning xml. And after reading this article, I am clear in namespaces atleast.

Hi,
I'm having a problem with xml namespaces.
My application accepts an xml document from another application, which is then validated using an xsd. The xsd has a namespace defined and uses a prefix "ns1" for the tags. The application from which i am supposed to get my xml doc for processing keeps changing the prefix but the namespace URI is the same. This causes the xsd to throw an error.

Is there any way by which the xsd can accept any prefix from the same URI?
