URN

[Hakan Akkaya]

Hi all,
i�m using messaging style Webservices and i have tried to to send a xml-File , which i had generated with Xml Spy from a xsd i had written.
My Problem is that i have to set the urn in the xml-file as following:
<Request xmlns="urn:WebServiceUrn" ...>
what i would like to know is if it�s possible to set the urn like this :
<Request xmlns:s="urn.... >
When i try to set this, i�m getting the Error:
service '' unknown
Can anyone tell me how to set the urn by using this term : xmlns:s and how to deploy this?
Thank you very much and excuse my english
