- Shouldn't 1003.0 step in here and exert some coordination?
- 1003.1 was deliberately not split into "levels" a la COBOL,
- and we meant it. A Real-Time extension could very well exist
- (say, number 1003.123a) and not require that 1003.1 be specified,
- but be useless in the absence of some subset of 1003.1 or equivalent,
- just as a hosted C implementation on UNIX does not specify that
- open() exist, but secretly requires a function with similar
- properties in order to be implemented at all. If the problem is
- that the extension wants to contradict some of 1003.1, then it is
- an INCOMPATIBLE standard (i.e. one could not specify simultaneous
- conformance with 1003.1 and 1003.123a), and I thought that standards
- organizations prohibited that.
