       Excel::ValueReader::XLSX has two possible implementation backends for parsing "XLSX" files :
       Excel::ValueReader::XLSX::Backend::Regex, based on regular expressions, or
       Excel::ValueReader::XLSX::Backend::LibXML, based on the libxml2 library.  Both backends share some common
       features, so the present class implements those common features. This is about internal implementation;
       it should be of no interest to external users of the module.
