11.6 HyTime system declaration

A HyTime system declaration specifies the version of HyTime and all of the modules and optional facilities that a HyTime system can support. It is represented by a set of HyTime support declarations in the reference concrete syntax. There must be one option attribute for each supported module, within which there can be no duplication of option names. The module and option names appear in the system declaration in the same order that they appear listed in this International Standard.

The system declaration for a system that supports all of the modules and optional facilities of HyTime is:
