[Zope-dev] dtml-var missing

[Andrew Lahser]

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.
