Sure, but that wasn't what Einstein wrote.

correct (without the insult, of course).

There wasn't a function named ξ in Einstein's text.

Because x' has a Latin letter 'x' in it, it was meant as a coordinate 
belonging to system K.

Therefore the equation ξ = x - vt was meant, while x' = x - vt was written.

x' should be capable of reflecting a light beam, hence a mirror should 
be placed there.

This would fit to the term 'If we place x' = x - vt...' but not to the 
equation.

That's why it is hard to say, what actually was meant with x'.

But that " τ = t' = t " wasn't, what Einstein had in mind.

No, the point x' MUST be stationary in K !!

If it is stationary in k, if would not move in respect to the emitter in 
the center of k and we had no use for the velocity v.
