How to define attribute existing for both ArrayItemAttribute and
ArrayItem.in XML Serialization using C#

Here is what my XML should look like after serialization using C# . Please
let me know how to define the C# classes for this.
<select disablesorting=\"false\">"
<option attrib1="aa" attrib2="xx">fgdgf</option>
<option attrib1="aa" attrib2="yy">fgdgf</option>
</select>
Thanks in advance.
