How to create a XML Schema Collection and use it in Fluent nHibernate?

Question

I'm looking forward to generate our database script by using the script generated by nHibernate. We use Fluent nHibernate to create our mapping.

In our original database design, there is a few xml columns that use the following schema:

CREATE XML SCHEMA COLLECTION LocalizedValue AS 
N'<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema"&gt;
  <xs:element name="Values">
    <xs:complexType>
      <xs:sequence>
        <xs:element maxOccurs="unbounded" name="Value">
          <xs:complexType>
            <xs:simpleContent>
              <xs:extension base="xs:string">
                <xs:attribute name="Culture" type="xs:string" use="optional" />
              </xs:extension>
            </xs:simpleContent>
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>'

And when we want to use it, we define our column like this (sample table):

CREATE TABLE Plans( PlanId int IDENTITY(1,1) NOT NULL, [Name] xml(CONTENT [dbo].[LocalizedValue]) NULL )

How can I achieve such feature by using nHibernate and/or Fluent nHibernate?
