A target of leafref to be referenced must be enabled when the require-instance property of the leafref is 'false'?

[hansammy-suh]

I've got this error and YANG cannot be compiled normally.

cannot load module: Not found node "A" in path.: Schema path: /path/.../A/.../target-leaf: Target of leafref "leaf" cannot be referenced because it is disabled.: Schema path: /path/.../A/.../target-leaf

In .yang file, the abstraction of the leaf is below """ leaf target-leaf { require-instance false; path "/path/.../A/.../target-leaf" }

According to the spec RFC7950, a target of leafref to be referenced must be enabled when the require-instance property of the leafref is 'false'?
