variant (Variant)

This element can contain exactly 1 child element of any variant type. This element is only valid as a child element of a vector or array variant type.

[Example: A vector of variant types:

<vt:vector baseType="variant">  
  <vt:variant>  
    <vt:i4>12</vt:i4>  
  </vt:variant>  
  <vt:variant>  
    <vt:lpstr>WorkSheets</vt:lpstr>  
  </vt:variant>  
</vt:vector>
