append ".." (because ' "/.." for the latter case respectively ' should 
be applied for the last case only)


Please note Action-49

I tried to stay as close as possible to the original text, but maybe a 
complete rewording might simplify the processing.

Eg. : Loosely speaking something like: 

Complete ".." path segments eat the previous segment, iff it is not a 
".." segment by itself.  Complete ".." segments accumulate to the left 
if the URI reference is relative and no path segments to be eaten 
appear, if however the URI is absolute complete ".." segments disappear 
when they hit the root slash ...

and so on ... treating "//", ".", "/./" and so forth

Konrad
