3 This hypothetical concept is chosen in preference to a real <strong>SNOMED</strong> CT concept to allow illustration of<br />

theoretical points with simple qualifiers. While all the points illustrated apply to some <strong>SNOMED</strong> CT concepts<br />

but there is no single concept that readily illustrates all these points without introducing other issues or having<br />

a long name that complicates the illustration.<br />
