So you want to differenciate between a property set to null and a
property that does not exist ? If your issue is that the document may
not have PR then you can't use custom properties in Contex to passe
informations since there won't be any way to access it.
Another way that should do it is to set properties in script context
using something like:
services.component.getInstance(org.xwiki.script.ScriptContextManager.class).setAttribute("DoCleanup",
true, javax.script.ScriptContext.ENGINE_SCOPE);
and then access it in Velocity using:
$DoCleanup
