MIME/base64 encoded files in an XML document?   

I have a schema for XML docs in which I need to handle embedded binary files. 
I defined it with mime/base64 encoding and am looking for advice about 
whether this is the right approach to handle this:

 <xs:complexType name="AttachedFile">
    <xs:sequence>
      <xs:element name="FileName" type="xs:string">
        <xs:annotation>
          <xs:documentation>Name of the attached file</xs:documentation>
        </xs:annotation>
      </xs:element>
      <xs:element name="Description" type="xs:string" minOccurs="0">
        <xs:annotation>
          <xs:documentation>Description of the attached 
file</xs:documentation>
        </xs:annotation>
      </xs:element>
      <xs:element name="DateAttached" type="xs:dateTime" minOccurs="0">
        <xs:annotation>
          <xs:documentation>Date that the file was attached to the 
application</xs:documentation>
        </xs:annotation>
      </xs:element>
      <xs:element name="File" type="xs:base64Binary" minOccurs="0">
        <xs:annotation>
          <xs:documentation>The attached file in MIME (base64) encoded 
format</xs:documentation>
        </xs:annotation>
      </xs:element>
    </xs:sequence>
  </xs:complexType>

Thanks!

That schema snippet looks all right to me.
