...which was deliberately represented in an asymmetric way, to verify the
design's ability to cope with such implementation intricacies. So basically
we have to kick in at LEVEL == 1 and access the implementation differently.
This exercise just shows again, that treating tree structures recursively
is the way to go, and we should do similar when coding up the query-API
for the real GTK toolkit based window elements...
this fixes a silly mistake:
obviously we want named sub-nodes, aka. "Attributes",
but we used the anonymous sub-nodes instead, aka. "Children"
Incidentally, this renders the definitions also way more readable;
in fact the strange post-fix naming notation of the original version
was a clear indication of using the system backwards....
the intention is to rely solely upon this abstract interface
in order to navigate the structure of the actual UI, so the
resolution process remains decoupled from the technicalities
of the actual UI toolkit set.
Through implementation of the corresponding unit test we'll determine
what it actually takes to build such a path resolution algorithm...
