When defining a data item, the ACU-style COMP-2 data item (that is, a data item under the effect of COMP2"DECIMAL") is unsupported.
By its nature, XML has no limits on data item size. COBOL does have size limitations for its data items. Many XML documents have been standardized and such standards include limitations on data items, but the COBOL program must still be written to deal with data item size constraints. When a nonnumeric data item is truncated on import, a warning status value is produced by XML Extensions.
