* Need to have this mirror class of {@link XSSFRelation}
* because of conflicts with regular ooxml relations.
* If we failed to break this into a separate class, in the cases of SharedStrings and Styles,
* 2 parts would exist, and "Packages shall not contain equivalent part names..."
*
* Also, we need to avoid the possibility of breaking the marshalling process for xml.
