This feature was added intentionally. Additionaly, <dtml-var x missing="Your x is not defined."> This will print the representation of x if it is defined. Or "Your x is not defined" if x is not defined. Also, the following entity syntax is possible. &dtml.missing-x; This change was checked into CVS Nov. 5, 1999, so it should have always been a part of the 2.1 release.

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? :)
