-----------------------------------------------------------------
[~rr...@adobe.com] perhaps the description isn't clear -- the "list" is
populated as part of the request. The thesis being that only the party sending
the request knows what is necessary to handle it.
IIOW, this is about allowing the request to make assertions as to how it needs
to be handled (which is similar to the extant {{:operation}} parameter).

> Project: Sling
> Issue Type: Improvement
> Components: Servlets
> Reporter: Justin Edelson
> Assignee: Justin Edelson
> Fix For: Servlets Post 2.3.16
>
>
> I would like to add support for a new "special" request parameter understood
> by the Sling Post Servlet named {{:requiredPostProcessors}}. This parameter
> may contain a comma-delimited list of names (see below) which *must* be
> available *at the time the request is processed* in order for the request to
> be handled. Whether or not those processors _do_ anything or whether the
> request succeeds or not is a separate question; this is just a preflight
> check if you will.
> If any of the required SlingPostProcessors are not available, the request
> will fail with a 501 error.
> The name of a SlingPostProcessor will be defined by a newly defined service
> registration property {{postProcessor.name}} and default to the simple name
> of the SlingPostProcessor's implementation class if that property is not
> defined.
