 In February 1994, the PWI Specification Committee sent a draft specification to X/Open—who rejected it in March, after being threatened by Microsoft's assertion of intellectual property rights (IPR) over the Windows APIs—and the European Computer Manufacturers' Association (ECMA).In September, now part of an ECMA delegation, they made an informational presentation about the project at the ISO SC22 plenary meeting in The Hague, Netherlands.Their goal was to make it an ISO standard in order to force Microsoft to comply with it (in Windows) or risk not being able sell to European or Asian governments who can only buy ISO standards-compliant products.
