(18) Annex B - flow and potential, should these be global keywords?
May not be a big of an issue after 1364 pulled the rug out from us on the section specific keywords. Should we go back to one
single list?
Recommendation: Consider impact of single list of keywords. Must move potential and flow to global keywords (from B2 to B1)
as they are needed in accessing attributes (see 5.2.2)
