Internal technical details
For evaluating the condition the template uses the actual parser function; however, not directly with p and q, because this strips spaces and newlines from the result, but with index values 1 and 2. The result can be 1, 2. The template with the applicable name is called (Template:P1 or Template:P2), with as parameters p and q.
