/*
Important:
 
Please note that JXLDDelimiterInsensitiveComparison is processed before JXLDWhitespaceInsensitiveComparison and JXLDWhitespaceTrimmingComparison.
This results is that the affected delimiter characters are effectively being removed before the comparison takes place
(all for the former option, only those at both ends for the latter).
