There were some mentions in the past, that a VSC can contain any sitemap component, so even actions, matchers and selectors are allowed in the definition of the VSC.

(I would say: no)
I would say yes! Forbidding control structures in virtual components would greatly reduce their usefulness.

Why would you *not* want this?
