      Description

      If a tab library contains both a function and a custom tag with the same name, they will overwrite each other. The one whose XML element in the TLD comes later wins (which for a valid TLD means that the function wins). That's first and foremost a backward compatibility problem, as before 2.3.22 the custom tag always won, because the function was ignored. Starting with 2.3.22 it can happen that you get a function instead of the custom tag, breaking an earlier working template. Also it would be good if we can support both behavior on the same time, be implementing both the TemplateMethodModelEx and the TemplateDirectiveModel interfaces.
