Nowhere to put OTHER status value

Status property should not be spread around many different psets

1

It's a real pain when filtering: https://github.com/IfcOpenShell/IfcOpenShell/issues/2741 This is similar to how MEP equipment have their size dimensions spread across many psets. There really should be a Pset_Status, also allowing...

Make Placement of IfcTextLiteral optional

2

Placement is currently mandatory for IfcTextLiteral. This seems inconsistent. I propose to make it optional (and therefore default to an identity matrix) which is the same behaviour for other types...

IfcCivilElement doesn't have CorrectTypeAssigned = IfcCivilElementType

IfcVirtualElementType or IfcAnnotationType should exist

1

Currently IfcVirtualElement and IfcAnnotation have no corresponding type. (e.g. so you can't have a type of dimension annotation) The only workaround right now is to use IfcTypeProduct which has this...
