struct Spec

A handle to a single spec stored in a layer. `Spec` is the untyped base used when retrieving a spec from a layer without knowing its concrete type. All concrete spec types (`USDPrim.Spec`, `USDPrim.Property.Spec`, etc.) conform to the nested ``MetadataCollection`` and ``FieldCollection`` protocols for shared metadata and field operations.
