Topic awaiting preservation: XML attribute issue

I'm not sure if this is an XML problem I have or C# or what, so if any MadSci feels like moving it, go ahead.

I have the following snippet (C#, same problem in 1.1 and 2.0):

XmlDocument xd = new XmlDocument();
XmlElement xe1 = xd.CreateElement("someXmlDoc");
xe1.SetAttribute("xsi:noNamespaceSchemaLocation", "C:\\schemas\\someXmlDoc.xsd");
xe1.SetAttribute("xmlns:xsi", "http://www.w3.org/2001/XMLSchema-instance");

xd.AppendChild(xe1);

string text = xd.DocumentElement.OuterXml;

The problem is that "text" looks like:

"<someXmlDoc noNamespaceSchemaLocation="C:\schemas\someXmlDoc.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" />"

The "xsi:noNamespaceSchemaLocation" atribute doesnt have the "xsi:" in it anymore... If I use something other than "noNamespaceSchemaLocation", it still loses the "xsi:"

Any idea where it went or what happened? I've done a little bit of searching around, but nothing has turned up yet.

Any sufficiently advanced bug is indistinguishable from a feature.

Checking the documentation, you can set the namespace by using three parameters:

public virtual string SetAttribute (
    string localName,
    string namespaceURI,
    string value
)

so it should probably be

xe1.SetAttribute("noNamespaceSchemaLocation", "http://www.w3.org/2001/XMLSchema-instance", "C:\\schemas\\someXmlDoc.xsd");

if I'm not totally mistaken.

I only had time right now to plug that in and try it, but it gives text a value of:

"<someXmlDoc d1p1:noNamespaceSchemaLocation=\"C:\\schemas\\someXmlDoc.xsd\" xmlns:d1p1=\"http://www.w3.org/2001/XMLSchema-instance\" />"

I'll look a little closer tomorrow at that and see if something doesn't flip a lightbulb on for me. Thanks.

[edit (note to self): seems that all I need is a way to set the "d1p1" to "xsi"...
