+ 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
+    * established signaling strings accompanying InnerSimulation=true:
+      - TRIGGER-MSG ... make the template execution emit messages
+                        describing changes being performed
+      - TRIGGER-RECURSION
+                    ... currently used in the oracle-like evaluation
+                        of what's the situation with the sibling
+                        elements as a recursion guard so that such
+                        nested runs won't revisit the new set of
+                        siblings per the respective nested context
