Well, actually I'm talking about the TagExtraInfo. With it, you can register variables in the tag scope... I would like to dinamically create these variables. I will not enter in details of why I want to do that, but it's relative to data access... It's possible or not? Maybe I can make a TagExtraInfo that grabs data from it related tag? That's possible? I mean, you have an "DoSomethingTag" and a "DoSomethingExtraInfoTag". It's possible to "DoSomethingExtraInfoTag" access ""DoSomethingTag" data?
