But, isn't there a way to supply a default value (if the variable lookup fails)?

Something like &dtml-variable default-value;

I think that would be stretching the semantics of <dtml-var> a bit beyond where they should go. Just wrap the entity in a <dtml-if> and test for the variable existence beforehand. Longer, but much more clear.

Would something like this be more palatable?

<dtml-var foo default="Empty">

How is this different from the following? <dtml-var foo null="default-value"> Drew
