  TRANSFORMATION HELPERS
 
  considerations, limitations, etc.:
  1. the transformations tries to preserve as much of the original XML
     as possible, incl. whitespace text/indentation and comments, but
     at times (corner cases of tricks A. + B. below), this needs to be
     sacrificed, e.g., distorting nice indentation, hence if the
     perfection is the goal:
     - user of the transformation can feed the minimized version of
       the XML (no denormalized/any white-space present)
     - user of the transformation can (re-)pretty-print the outcome
       afterwards
 
  tricks and conventions used:
  A. callable templates only return Result Tree Fragments, which means
     the only operations allowed are those looking at the underlying,
     virtual node-set, and since we need to discern their non-void
     production (i.e. on successful match/es), we use this trick:
     - ensure the template will not propagate any denormalized whitespace
     - inject denormalized whitespace (superfluous space) artificially
       to mark successful production (but see B. below)
     - with the template production, here stored as Var variable,
       we test "normalize-space($Var) != $Var" condition to detect
       non-void production, mainly intended to see whether to emit
       the enclosing element at all (with the goal of not leaving
       superfluous elements behind needlessly)
  B. [extension over A.] to eliminate distorted indentation
     (cf. consideration 1.), additional reuse of these callable
     templates is introduced: the template can recursively call
     itself with a special flag (InnerSimulation) as an oracle to
     see to whether non-void production will ensue (all pre-existing
     denormalized whitespace is forcefully removed in this mode),
     and if positive, all such inner pre-existing whitespace is
     then preserved in this outer=main invocation
  C. [extension over B.] when checking the non-void production
     (via InnerSimulation), beside the injected denormalized whitespace,
     we can also inject particular strings, which the callsite of such
     simulation can, in addition, inspect for paricular string
     occurrences, e.g. to prevent clashes on the production coming
     from multiple sources
  D. not only to honour DRY principle and to avoid inner entropy, it's
     often useful to make callable template bimodal, e.g., when the
     production is generated in the "what's to stay in place" vs.
     "what's to be propagated (combined with previous, effectively
     moved) at this other part of the tree" contexts; for such cases,
     there's usually InverseMode parameter to be assigned true()
     (implicit default) and false(), respectively
+ E. the common idiom that emerges is: evaluate simulation value,
+    depending on the presence of the "success mark" (cf. A.),
+    possibly emit non-simulation value; since it would (likely)
+    re-evaluate the simulation anew (wastefully) or perhaps
+    this sort of dependency injection can just come handy,
+    common transformation helpers below offer InnerPass
+    parameter to be optionally passed, either as a string (when
+    no-denormalized-space is an internal criterium for the template)
+    or, conventionally, the result tree fragment representing the
+    output of the template at hand called with a simulation flag
