[antlr-interest] invoke subtemplates on multivalue attribute

[Florian Barth]

Hi there!
Thank you for this hint. It works and the conds and thens are properly  
computed.
This solved problem number one, but the number two is still there.
If I feed the template with a list of values (that need further rules  
to be applied) the compiler still complains because of the multi- 
valued attribute:
[12:51:16] error(125): ResultGenerator.g:47:8: label conds type  
mismatch with previous definition: token-list!=rule-list
[12:51:16] error(125): ResultGenerator.g:48:8: label thens type  
mismatch with previous definition: token-list!=rule-list

I think this error message is related to the conds.st and then.st.  
With single values this works, but it is not applicable to multi- 
valued attributes.
I need to state something like
"for each value of value-list do
	apply further rules and apply the according template
return these values to super-template as list of evaluated strings"

Any ideas?
