Column selection as XML with namespace

Question

I need to select some columns from a table as XML with the included namespaces along with the other columns as they are. For example, I have the following table layout:

ID  C1  X1C1  X1C2  X2C3
1   A   1     2     3

Refund request:

ID  C1  XmlData
1   A   <xmldata1>
2   A   <xmldata2>

Where <xmldata1>will be:

<Root xmlns:xsd="w3.org/2001/XMLSchema" xmlns:xsi="w3.org/2001/XMLSchema-instance" xmlns:mst="microsoft.com/wsdl/types/">
  <Child attrib="C1">
    <ChildValue xsi:type="xsd:integer">1</ChildNode>
  </Child>
  <Child attrib="C2">
    <ChildNode xsi:type="xsd:integer">2</ChildNode>
  </Child>
</Root>

and <xmldata2>:

<Rootxmlns:xsd="w3.org/2001/XMLSchema" xmlns:xsi="w3.org/2001/XMLSchema-instance" xmlns:mst="microsoft.com/wsdl/types/">
  <Child attrib="C3">
    <ChildNode xsi:type="xsd:integer">3</ChildNode>
  </Child>
</Root>

I have a good link on how to build xml from this SO question , but I cannot put namespaces. If possible, how to do it?

Edit: I used the following query trying to get the desired result: select 1 ID, 'A' C1, 1 X1C1, 2 X1C2, 3 X2C3 in #t

;with xmlnamespaces('w3.org/2001/XMLSchema' as xsd, 'w3.org/2001/XMLSchema-instance' as xsi, 'microsoft.com/wsdl/types/' as mst)
select ID, C1, (select (SELECT 'C1' "@attrib", 'xsd:integer' "ChildValue/@xsi:type",t.X1C1 as 'ChildValue' FOR XML PATH('Child'), type),(SELECT 'C2' "@name", 'xsd:integer' "ChildValue/@xsi:type", t.X1C2 as 'ChildValue' FOR XML PATH('Child'), type) FOR XML PATH('Root'), type) as property_data 
FROM #t t

drop table #t

Here is the result of its xml part:

<Root xmlns:mst="microsoft.com/wsdl/types/" xmlns:xsi="w3.org/2001/XMLSchema-instance" xmlns:xsd="w3.org/2001/XMLSchema">
<Child xmlns:mst="microsoft.com/wsdl/types/" xmlns:xsi="w3.org/2001/XMLSchema-instance" xmlns:xsd="w3.org/2001/XMLSchema" attrib="C1">
    <ChildValue xsi:type="xsd:integer">1</ChildValue>
  </Child>
  <Child xmlns:mst="microsoft.com/wsdl/types/" xmlns:xsi="w3.org/2001/XMLSchema-instance" xmlns:xsd="w3.org/2001/XMLSchema" name="C2">
    <ChildValue xsi:type="xsd:integer">2</ChildValue>
  </Child>
</Root>

I cannot get rid of namespaces in Childnode.

(SELECT 'C2' "@name",t.C2 as 'value'FOR XML PATH('property'), type)
FOR XML PATH('data'), type) as property_data 
FROM TableName t
