Discussion

Thestatuscodeandreasoncodedefinitionscouldbeimproved:

∙Someofthemaredefinedusinganexplanatoryparagraph,soanalternativeformofrepresentationisneededinClause6,whereshortnamesratherthanessaysarerequiredforenumerationlists.

∙Sometimesthemappingbetweenclause6namesandclause8assignmentsisunclear.

∙Thislackofclarityresultedinmappingtables,suchasin10.4.4.

oThismappingtableessentiallyprovidesashortnameforasubsetofStatusCodevalues.

oThedanger（realizedmultipletimes）isthatpeopledon’trealizethisisthesamenamespaceas（inthiscase）theStatusCodevalues,andgroupsallocatethemselvesvaluesindependentlyfromtheStatusCodetable.

oThishappenedrecently,andeventheANAmisunderstoodwhatwashappeningandallowedindependentallocationsfromthissubsetnamespace.

Ibelievethefollowingfixupsarenecessary:

∙Adda“name”columntostatuscodeandresultcodetables.

∙Removeany（Clause10）mappingtablesofshortnametoStatusCodeorReasonCodebymergingtheirnamecolumnsintothestatuscodeorresultcodetables.

∙EnsurethateachenumerationvalueusedinClause6mapsexactlyontothenamefieldofaClause8Status/Reasoncodetableentry,addingnewcodesasnecessary,oraddingnamestoexistingentrieswherethereisaclearcorrespondence.

∙ReplaceanyrecentadditionsinClause6thatusethe“essayform”torefertooneofthesecodeswithashortername,andaddnamestostatus/reasoncodestosupportthisasnecessary.

∙Ensureconsistencybetween.confirmand.responsebymakingtheenumeratedlistofthe.confirmcontainallthevaluesinthe.response.
