How to add non-native attribute to XmlSchema in .NET

[Eric]

I am building an XML Schema with the SOM in .NET and would like to add
a non-native attribute to one of my elements. Does anyone know how to
do this? (Whithout rendering the schema to an XmlDocument to do it.)

Thanks!
Eric

What do you mean "non-native"?
If that means non-schema attributes (some proprietary attribute say on
xs:element) you can add it by filling UnhandledAttrib utes collection.

Oleg, thanks for the reonse.

Yes, I mean non-schema attributes. UnhandledAttrib utes is an array of
XmlAttribute objects. This looks like it is meant to be used when
reading a schema file. How would I use it in building the schema file?

Hmm, really. I've got no better idea than using dummy XmlDocument:
XmlSchema schema = new XmlSchema();
XmlSchemaElemen t elem = new XmlSchemaElemen t();
elem.Name = "foo";
elem.SchemaType Name = new XmlQualifiedNam e("string",
"http://www.w3.org/2001/XMLSchema");
XmlDocument dummyDoc = new XmlDocument();
XmlAttribute attr = dummyDoc.Create Attribute("myns :blah",
"http://myns.com");
attr.Value="my own attribute";
elem.UnhandledA ttributes = new XmlAttribute[] {attr};
schema.Items.Ad d(elem);
schema.Write(Co nsole.Out);

Produces:
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element myns:blah="my own attribute" name="foo" type="xs:string "
xmlns:myns="htt p://myns.com" />
</xs:schema>

</xs:schema>

That gives me exactly what I was looking for. Thanks! It would have
been nice if .NET classes made this a little more straightforward , but
it least it works.
