Yeah - I don't think there is any way for YANG to really express different defaults (i.e. dynamic defaults that depend on some other condition, e.g. which list item, etc). The YANG default statement is really only for leafs that have a static default value (i.e. always the same). In this case the best you can do is have no YANG "default" statement and maybe describe the situation in the description (which won't really be machine readable).

I tried by having conditional leaf nodes (using when on type) but I can't have duplicate leaf-nodes in the schema, even if the 2 when statements can never be true at the same time. Suggestions? You can make clever use of the "union" data type to allow different defaults. You cannot really represent the conditions to pick a member type (except description). Regards, Reshad.
