Apparently, ePubcheck accepts only SVG 1.1 images without RDF metadata, even though ADE/RMSDK displays these files just fine.

However, you can easily fix this by implementing the following changes:

1. Delete xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
2. Change version="1.2" to version="1.1"
3. Delete the <rdf:RDF> ... </rdf:RDF> section

The header should look like this:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!-- Created with Inkscape (http://www.inkscape.org/) -->

<svg
   xmlns:dc="http://purl.org/dc/elements/1.1/"
   xmlns:cc="http://creativecommons.org/ns#"
   xmlns:svg="http://www.w3.org/2000/svg"
   xmlns="http://www.w3.org/2000/svg"
   version="1.1"
   width="511"
   height="245"
   id="svg3021">
  <defs
     id="defs3025" />
  <metadata
     id="metadata7">
  </metadata>

If you implement these changes, you shouldn't get any SVG-related validation errors.
