@ericstewart hmm I haven’t see anything like that ... spec could validate values but it wouldn’t be too closely tied to form element
I think the spirit of it is in a project like re_form (https://github.com/HealthSamurai/re-form), which is specific to re-frame apps (described here a bit more). I think the idea is that we can already generate swagger/openapi descriptions or JSON-Schema descriptions from specs, so may be possible
