[Zope-dev] dtml-var missing

[Stephan Richter]

I found an undocumented feature today-
 <dtml-var  x  missing>

This displays x if x is defined (but if it is None, then the word "None"
is displayed.) If x is not defined then nothing is displayed and there is no
error.

So, I put this in ZQR but now I am thinking - is this an undocumented
feature by mistake or did you intend to deprecate it and so it is undocumented
for a reason?

Any other undocumented feature I should know for an important project? 
:)
