> As XML has XSD, so CSV needs an external schema definition file which defines the schema of the flat file format and the values it contains.  Programmatically adding constraints, as supported by {{org.supercsv.cellprocessor.constraint.StrRegEx}}, are useful but not portable.  Fortunately, Microsoft has already created such a CSV schema definition file format called [Schema.ini|http://msdn.microsoft.com/en-us/library/ms709353(v=vs.85).aspx].
> It is my suggestion to add file and data parsing validation to Apache Commons CSV by adopting support for _Schema.ini_, bringing this long overdue functionality to the Java world.
