Typename collide!

Hi,

I am trying to validate a schema (say sample.xsd) using MSXML, and end
up getting the following error 

 

"The Schema has a TypeName that collide with the RootNode TypeName of
one of its root nodes. Make sure that they are different"

 

When I try to validate other XML tools it validates well and good.

So is this above error something unique to MSXML or is it one of W3C
Namespace specification?

 

Also, when I change the XML schema name to something else it works fine
even within MSXML. Also please note that there is a element type name in
the schema same as the schema file name!

 

Thanks

Raj
