XML Schemas for syndication

Hello everyone:

I'm using XML Schemas for syndicating data, however, I need to add a namespace for XI to catch the xml and distribute the data.

The xsd file is:

<?xml version="1.0" encoding="UTF-8"?>

http://www.w3.org/2001/XMLSchema" xmlns:ns=" http://sap.com/xi/XI/MyDemos/DemoADD">

<xsd:element name="MsgTypeSynFADIC0">

<xsd:complexType>

<xsd:sequence>

<!-- my data -->

</xsd:sequence>

</xsd:complexType>

</xsd:element>

</xsd:schema>

and I get something like this:

<?xml version="1.0" ?>

http://sap.com/xi/XI/MyDemos/DemoADD">

<!-- my data -->

</MsgTypeSynFADIC0>

however, I need something like this:

http://sap.com/xi/XI/MyDemos/DemoADD">

<!-- my data -->

</ns:MsgTypeSynFADIC0>

So I need the nd: prefix before the rootElement. I've tried XML/XSD editors but when I feed Syndicator with those the rootElement desapears and I can't create a Syndication File.

What can I add to the schema file so I get the ns: prefix?

Thanks

Regards

Alejandro
