Thanks for a great explanation (well, I had to read it two or three 
times to understand it).

So it's double "|" that make logical sense (||), not single "|" (|). I 
thought a single "|" makes some sense, no wonder I got weird results :)

In other words (perhaps only I can understand my own explanation, but well):

doNotShowLink = 1 || 0 |*| 1 |*| 0

means we have 4 parts, which are split by || or |*|:

1) logical yes, 1, (or, not show the first link), for the first element
2) logical no, 0, (or, not doNot show -> show) for the second element
3) all following elements take logical yes, 1 (don't show), because of 
|*| 1 |*|
4) the last element, no, 0 -> show it


Now that I think I understand it, I have yet another logical challenge. 
I hope I'm no being too demanding :)


Out of page subtree, when on "page4":

page1 > page2 > page3 > page4


I can display:

page2 page4


What I actually want to display is:

page2 - page4


No problem - add:
1.CUR = 1
1.CUR.linkWrap = -|


And it will render:

page2 - page4  # when on page4
page2 - page3  # when on page3
- page2        # when on page2 - problem

Oops, a single hyphen in sot needed!

So we can't use CUR.linkwrap for that, we have to figure out something else.


wrapItemAndSub also doesn't seem to work for that for the same reason as 
CUR.linkwrap.

And there is no such thing as wrapSub, which would work for subitems only.

Hmm. Did I miss anything in TSRef which allows me to achieve it?
