This describes a "MACROBUTTON" field which can run a designated macro or command. But there is no mention of what programming language or API’s are allowed for such a designated macro or command.
If this is to be "implementer defined," the text should so indicate in a clear and unambiguous way.
Part 4, Section 02.16.05.41

Proposed Disposition of DIS 29500 Comment CA-0026 (Modified: 2007-11-29) Agreed it is outside the scope of this Standard to attempt to define any application’s runtime APIs; however, the current text leaves this mechanism unspecified. To address this, the following sentence will be added to Part 4, §2.16.5.41, page 1,545, lines 2830: The mechanism by which the command specified by text in field-argument-1 is located and/or executed by an application is implementation-defined.
