The orientations of the axes (of x, y and z) were not mentioned, but I use this setting:
x points right
y points 'inside' (if x and z define a two-dimensional plane, like the one you draw on)
z points up (because z is usually used for hight)

Usually you need to find a way, by which things get names in a consistent manner, which the reader could eventually remember

 What you say is very interesting.
 

Well, thanks.
But this isn't such a nice story at all.
In a way this problem with naming coordinate systems was just the 'tip of the iceberg'.
But the reuse of symbols or -for instance- to define something one way, but not sticking to this definition, are also observable.
Especially annoying were the reuse of the letter A and the symbol x'.
There were actually eight different uses for the tall latin 'A' in this paper.
But how could any reader keep track of the intended meaning in a certain context?
