I'm not 100% certain the action item is related to this, but during the 
F2F I had asked the Interest Group for opinions on the various 
ways of modelling 'controlled values' for a property:

-  as a closed set of literals
-  as an enumerated class (nominals / owl:oneOf)
-  as a class constructed by union (disjunction / owl:unionOf).

It was in the context of the bypass surgery usecase [1] and how you might 
model a controlled list of vessels.

The example was 'Coronary Artery stenosis is a class of heart disease
associated with one of many coronary vessels - each of which with a specific anatomical location':

Class(CoronaryArteryStenosis complete

          restriction(associatedArtery allValuesFrom CoronaryArtery)

I. Nominals (where each vessel is an individual and an instance of 

Class(CoronaryArtery complete

II.  Disjunction - where each vessel is an instance of the unique kinds of 
Coronary Arteries

Class(CoronaryArtery complete

The former is more amenable for expressing & reusing controlled / coded 
vocabularies (such as HL7 for instance) and easier to implement visually 
as a pick list (for data collection purposes), the latter allows you more 
flexibility to use foundational ontologies such as FMA [2] 
to be precise about the anatomical relationships and descriptors. 
However, what you gain in a more precise description, you lose (may?) in
