omitting xml guess instruction serializing an object

i'm serializing an vigilant c# vs2003 / .net 1.1 application. i need serialized but guess instruction, however. xmlserializer category puts out something this:

<?xml version="1.0" encoding="utf-16" ?> 
<myobject>
    <property1>data</property1>
    <property2>more data</property2>
</myobject>

is there any proceed something following, but guess indirect calm mislay tag?

<myobject>
    <property1>data</property1>
    <property2>more data</property2>
</myobject>

for those curious, formula looks this...

xmlserializer serializer = new xmlserializer(typeof(myobject));
stringbuilder builder = new stringbuilder();

using ( textwriter stringwriter = new stringwriter(builder) )
{
    serializer.serialize(stringwriter, comments);
    relapse builder.tostring();
}
