/**
 * Uses rule based parsing to read the EML XML and build the EML model.
 * Note the following: - Metadata provider rules are omitted on the assumption that the provider is the same as the
 * creator - Contact rules are omitted on the assumption that contacts are covered by the creator and associated
 * parties - Publisher rules are omitted on the assumption the publisher is covered by the creator and associated
 * parties//from w  w w. ja  va  2  s . c  o m
 *
 * @param xml To read. Note this will be closed before returning
 *
 * @return The EML populated
 *
 * @throws IOException  If the Stream cannot be read from
 * @throws SAXException If the XML is not well formed
