p2p.wrox.com Forums - "Root Element Missing" error creating custom columns

Custom site column deployment fails with "Root Element missing" error. Using sample right out of the book. Could anyone tell me what's wrong or how I can debug?

See below.

Code:

<?xml version="1.0" encoding="utf-8" ?>

  <ElementManifests>

    <ElementManifest Location="MyCustomColumn.xml" />
