I personally don't remember a thread about have return values for tags, but most tags do put things into the JellyContext with their 'var' attribute and there is also the j:set tag for setting a variable which we use as a 'return type'.
Even with that however, we use Jelly as an all purpose scripting language without the XMLOutput. In most cases we even modularize it and use the import tag to having one script invoke another script. We then use the JellyContext to get out all of the values that we are looking for. Yes it will contain other things you don't need, but in our case anyway, we don't particularly care about that.

The way it is done into such things as jelly-swing is that the tag climbs the hierarchy to the first possible ancestor tag that can receive a result and "adds" it there. (namely, this is how a component is added to a container). There has been a long thread however about having return values for tags.
