[news.eclipse.webtools] Problem during replacing element from one schema

[bhuvanmehta@xxxxxxxxx (Bhuvan )]

Hello,

I am trying to replace an element from one schema(source) to another 
schema(target) schema using DOM APIs as below :
and the replacement is not happening properly.

			e.printStackTrace();

------------------------------------------------------------------
Validation falis with below message
------------------------------------------------------------------
XSD: Type reference 'tns1#simple1' is unresolved, which is true as 
replacechild() method should have defined "tns1" in element ?

Am i doing something wrong or is there any other way to do this.
