Currently, value-set definitions are of the form:
```
["ac0.1"] = <
id = <"ac0.1">
members = <"at1", "at2", "at3", "at4", "at0.3", "at0.4">
>
```
However, to make redefinition easier, we want to be able to do the following:
```
["ac0.1"] = <
id = <"ac0.1">
members = <"ac1", "at0.3", "at0.4">
>
```
Where ac1 is assumed to be:
```
["ac1"] = <
id = <"ac1">
members = <"at1", "at2", "at3", "at4">
>
```
