Item Description

Codes defining conditions on the _item_type.code specification. 'esd' permits a number string to contain an appended standard deviation number enclosed within parentheses. E.g. 4.37(5) 'seq' permits data to be declared as a sequence of values separated by a comma <,> or a colon <:>. * The sequence v1,v2,v3,. signals that v1, v2, v3, etc. are alternative values or the data item. * The sequence v1:v2 signals that v1 and v2 are the boundary values of a continuous range of values. This mechanism was used to specify permitted ranges of an item in previous DDL versions. Combinations of alternate and range sequences are permitted.
