CDM XML Parser should ignore empty not mandatory fields
The CDM Parser should ignore empty not mandatory fields by parsing CDM in XML format. At the moment, empty tags like <START_SCREEN_PERIOD nil=“true”/> or <START_SCREEN_PERIOD /> or <START_SCREEN_PERIOD/></START_SCREEN_PERIOD> raise exception reading CDM file from JSPOC.
The issue does not occurr if the optional fields are not present at all.
