 * Performs a Schematron validation of the DDMS Resource, via the ISO Schematron skeleton stylesheets for XSLT1

 * to the DDMS specification.
 * 
 * <p>The informational results of this validation are returned to the caller in a list of ValidationMessages of
 * type "Warning" for reports and "Error" for failed asserts. These messages do NOT affect the validity of the
 * underlying object model. The locator on the ValidationMessage will be the location attribute from the
 * successful-report or failed-assert element.</p>

 * <p>Details about ISO Schematron can be found at: http://www.schematron.com/ </p>
 * 
 * @param schematronFile the file containing the ISO Schematron constraints. This file is transformed with the ISO
 *        Schematron skeleton files.

 * @throws XSLException if there are XSL problems transforming with stylesheets
 * @throws IOException if there are problems reading or parsing the Schematron file
