  This is a RELAX NG schema for the output of 'virt-inspector'.

  To validate an existing document against this schema, you can
  use xmllint, like this:

    virt-inspector -d Foo > output.xml
    xmllint - -noout - -relaxng virt-inspector.rng output.xml

  (Note that because of limitations of XML, I have had to put spaces
  between double dashes in the above code.  Those spaces should not
  be there in what you type on the command line).

  Veillard.
