Re: [Zope] The XML-dtml notation "&dtml-variable;"

Hi, I just learned about the XML-dtml notation for inserting values inside XML-strings.

I find this useful, and use it both in HTML and XML.

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. -Michel
