Please forgive what may be a very n00b question . . . but I've noticed that the XML tags in each asset file are pretty generic, and some are identical in different assets. So, could I use a tag not originally listed in an asset, as long as it's listed elsewhere? For example, could I build an "Innovative" trait in the TraitInfos file just by using a few of the same XML tags in the Library section of the BuildingInfos file, even though those tags aren't listed in any other Trait?
