It would require C coding to get it nicely, I see three options:
- try to get the values as in branch_route -- seems complex at first look
- try to get the values via $T_branch(attr) -- sounds simpler now
- try to get a function t_reuse_branch() -- create a new branch from
current one so you can just relay
As an option to implement now, try using hash table to store attributes
using keys like:
$sht(t=>$T(id_label)::$T(id_index)::$T(branch_index)::ru) = $ru;
$sht(t=>$T(id_label)::$T(id_index)::$T(branch_index)::du) = $du;
Then use them to create the new branch.
But avps are per transaction, not per branch, so if you add one, will be
visible to all branches (same should be in branch_route).
