I commited the bugfix to HEAD earlier this morning. I hope to add documentation to acs-templating for the undocumented name=""/value="" functionality, as well as give examples of what works and what doesn't with nested <lists>.
The ONLY thing I changed was to modify the index variable in a for loop.
"for {set __ats_i.." ==> "for {set __ats_${name}_i..."
This has no impact on current behavior. I will add some test cases in the next few days, to demonstrate the viability of the fix. Hopefully it can be proved and moved to the 5-1 branch for release.
