[stringtemplate-interest] Listing of used Attributes (@Caleb)

[Dreyer Ulf (CR/APA3)]

Hello Caleb, 

you wrote on the ANTLR/ST-Wiki about the possibility of
listing the attributes a StringTemplate uses/has looked for.
Since I have exactly this problem (albeit in a simpler case)
I would love to read more about this on the list or in the wiki.

Could you extend your Wiki entry with the mentioned methods?

I'd like to find out about all used Variables (preferably beforehand)
in a scenario where there are no indirect calls (as in
<(expr)(argument)>).

The second you method is finding out the attributes AFTERwards.
Is this also possible with an empty Attribute-Set?
(Again in my scenario where I don't use attributes to reference
templates/properties)

Thanks

Ulf
