noNamespaceSchemaLocation and schemalocation

[igoritkin]

I need held with XML and XSD. May be somebody have a sample, how to built XML with combined noNamespace and Namespace and how to validate it against two various schemes?

XML must be as following:
<Root
xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespace SchemaLocation= "Schema_v1_1.xs d"
xsi:schemaLocat ion=
"http://www.custum.com Schema_v1_2.xsd "
xmlns:t="http://www.custom.com" >
<Node1>
<Node2/>
<Node2/>
</Node1>
<t:Node>
<Node2/>
<t:Node2/>
</t:Node>
</Root>

Schemas must have the same structure.
