Setting a reference to a schema doesn't work?

Hello NG!

Using the System.Xml.XmlDocument I want to create such a xml-file:

<?xml version="1.0" encoding="utf-8"?>
<RootElement xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="RootElement.xsd ">
....
</RootElement>

(That's what XMLSpy generates when assigning a schema to an xml-file.)

I tried...
pDoc = New System.Xml.XmlDocument
pDoc.AppendChild(pDoc.CreateXmlDeclaration("1.0", "utf-8", ""))
pRoot = pDoc.AppendChild(pDoc.CreateElement("RootElement") )
pRoot.Attributes.Append(pDoc.CreateAttribute("xmln s:xsi"))
pRoot.Attributes("xmlns:xsi").Value =
"http://www.w3.org/2001/XMLSchema-instance"
pRoot.Attributes.Append(pDoc.CreateAttribute("xsi: noNamespaceSchemaLocation"))
pRoot.Attributes("xsi:noNamespaceSchemaLocation"). Value = "RootElement.xsd"

But then I get
<RootElement xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
noNamespaceSchemaLocation="RootElement.xsd">

So the Prefix "xsi" for "noNamespaceSchemaLocation" is missing and the file
can't be validated, because this attribute is "unexpected". What's wrong
with that code? How can I produce a correct link to an schema?

Thanks,

Found it by myself...

The framework does more work than I expected. Using

pRoot = pDoc.AppendChild(pDoc.CreateElement("RootElement") )
pRoot.Attributes.Append(pDoc.CreateAttribute("xsi: noNamespaceSchemaLocation",
"http://www.w3.org/2001/XMLSchema-instance"))
pRoot.Attributes("xsi:noNamespaceSchemaLocation"). Value = "RootElement.xsd"

instead of

| pRoot.Attributes.Append(pDoc.CreateAttribute("xmln s:xsi"))
| pRoot.Attributes("xmlns:xsi").Value =
| "http://www.w3.org/2001/XMLSchema-instance"
|
pRoot.Attributes.Append(pDoc.CreateAttribute("xsi: noNamespaceSchemaLocation"))
| pRoot.Attributes("xsi:noNamespaceSchemaLocation"). Value =
"RootElement.xsd"

is enough.
