Enum Path 

pub enum Path {
    Forward(&'static str),
    Inverse(&'static str),
    Alternative(&'static [AltBranch]),
    Chain(&'static [Step]),
}

Where a property shape’s values come from.

Field keys are the local XML element name with the prefix stripped, which is exactly what the decoder puts in cimmodel::Element::fields.

Variants

Forward(&'static str)

A field on the element itself.

Inverse(&'static str)

sh:inversePath — the field on whatever points at this element. Needs the reverse index, which is why [ShapeSet] tracks whether any active shape uses one.

Alternative(&'static [AltBranch])

sh:alternativePath — the union of every branch’s values. A branch may itself be inverse, hence AltBranch rather than a plain name.

Chain(&'static [Step])

A sequence path: ( ^cim:Terminal.ConductingEquipment cim:Terminal.phases ), ( cim:Location.mainAddress cim:StreetAddress.status cim:Status.dateTime ), and — 170 of NCP’s 178 chains, its main association value-type check — ( nc:X.y rdf:type ).

Stepping from an element absent from the dataset makes the result unknown and every check on it silent: phase 1 runs per file, so leaving the file is normal. A final rdf:type step needs nothing from the elements it reaches, so they count even when absent, and class checks skip the absent ones, as Constraint::RefClass describes.

The referenced element may belong to either family: NCP’s value-type lists name CGMES classes (cim17:ACLineSegment) alongside NC ones, and Element::type_name answers for both.
