Item Description

When a data value can be defined as a pre-determined sequence of characters, or optional characters, or data names (for which the definition is also available), it is specified as a construction. The rules of construction conform to the the regular expression (REGEX) specifications detailed in the IEEE document P1003.2 Draft 11.2 Sept 1991 (ftp file '/doc/POSIX/1003.2/p121-140'). Resolved data names for which _item_type_list.construct specifications exist are replaced by these constructions, otherwise the data name string is not replaced.
