Experimental code for %encoding of UTF-8 characters, commented out while
we work out what the problem description is and what the appropriate consistency policy should be.
Added facility to annotate the members of a list of property-value pairs. Added annotations
for odd and even members of a list, and for the last item in the list.
Requests generate a variable binding from _selectedView to the name of
the view that was used, with trailing .copy omitted.
Added limited in-to-out tests for binding _selectedView to the
selected viewer name.
WIP: changing to use hierarchy node structure, but need some revisions for multiple property-value pairs
