i dunno ... that seems like it would really kill the utility of a field for a lot of use cases
– if it had that kind of limitation, i would just use an "int" field an managing the mappings
myself so id always know i could add/remove (EDIT) fields values w/o needing to reindex.

This isnt really going to work here, because the idea is you want to assign sort order (not
just values mapped to ints). If you want to rename a label, thats fine, but you cant really
change the sort order without reindexing.

> We have encountered a use case in our system where we have a few fields (Severity. Risk
etc) with a closed set of values, where the sort order for these values is pre-determined
but not lexicographic (Critical is higher than High). Generically this is very close to how
enums work.
> To implement, I have prototyped a new type of field: EnumField where the inputs are a
closed predefined  set of strings in a special configuration file (similar to currency.xml).
> The code is based on 4.2.1.
