// Description:
// This test assumes the following setup:
// EComRomOnlyExampleOnC/10009DB6 on C:
// EComRomOnlyExampleOnZ/10009DB5 on Z:
// The tests work by checking that the correct implementations are chosen from two plug-ins, one on C:, one on Z:
// Implementation:		On C:					On Z:								Expected result:
// 10009DCA			version 2				version 1, not ROM-only				ECom selects version 2 on C:
// 10009DCB			version 2, ROM-only	f	version 1, not ROM-only				ECom selects version 1 on Z:
// 10009DCC			version 1				version 2, not ROM-only				ECom selects version 2 on Z:
// 10009DCD			version 2				version 1, ROM-only					ECom selects version 1 on Z:
// 10009DCE			version 1				version 2, ROM-only					ECom selects version 2 on Z:
// 10009DCF			version 3				version 1 & version 2, ROM-only		ECom selects version 2 on Z:
//
