IDSource is defined as String as of FIX 4.2, and allows 9 preset values (1 through 9), and a theoretically unlimited set of numbers starting with 100. However, there is no explicit limitation to use enumerations only.
Is anyone using a value of 100+, and if so, which values (if they are enumerations), and what do they mean?
Is anyone using alpha-numeric ‘codifications’ such as WKN / WPK, Valoren, etc?
