Two or more conceptsmay be combined to form a new concept by joining them with the "+" symbol. This is particularly useful where both concepts are primitive. The resultant expressionis the childof each of the conceptsin the expression. The resultant expression below represents a drug dose form that is both a spray and a suspension.
The syntax does not mandate which
expressionshould have associated terms and which should not, so it is valid (although not advisable)
to mix and match. For example, the following syntax is valid:
7946007 |Drug suspension|The syntax allows spaces, tabs and carriage returns in most places. The following
example has an identical meaning to the one above:
+ 7946007 |Drug suspension|
