I didn't say to remove the declaration, or to remove the prefix from
the attribute.  Your instance should begin:

  <proposals xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:noNamespaceSchemaLocation="file:///C:/My Documents/proposal1.xsd">

I encourage you to look at the Primer [1], or get an introductory XML
Schema book -- you seem to be a bit unfamiliar with how namespaces and
schemas work.
