18	3.7.7.2	ITS station	ITS component that provides a bounded secured managed domain and conforms to the ITS-S reference architecture\r\n EDITOR'S NOTE 1 As can be seen in a few examples, the phrase "network, comprised of applications" is ambiguous as it is unclear if the ITS-S is comprised of the items or if the network is comprised of the items.\r\n EDITOR'S NOTE 2 The proposed definition assumes that ITS-S are not required to have a wireless network interface. It is my understanding that any ITS device that conformed to the ITS-S architecture (which is almost a null requirement) and provides a BSMD (which is ill-defined) would be considered an ITS-S. Thus, at least at present, I see the term ITS-S to really mean any ITS physical entity that can claim to be secure (and it would be just a claim since there are no measurable requirements). And in fact, some definitions even make the BSMD optional - though I think this is wildly unwise.\r\n EDITOR'S NOTE 3 Logically, an ITS-S seldom (if ever) provides ITS services because an ITS-S is a component of an ITS network; the ITS service is provided by the ITS as a whole. The ITS-S logically should provide ITS-S services, or more specifically, the ITS-S is comprised of the ITS-S architectural components (i.e., applications entity, facilities layer, etc), which all provide ITS-S services. \r\n
