//! Door and window lining properties.
//!
//! # Paired attributes
//!
//! The lining rules are pairing constraints, and door and window state
//! them differently. A door's transom and casing pairs are XOR: both or
//! neither. A window's transom and mullion offsets are ordered: the
//! second may only appear when the first does. Writing one half of
//! either pair produces a file that parses and reports a dimension
//! nothing can interpret.
//!
//! # Release
//!
//! [`add_door_lining_properties`] and [`add_window_lining_properties`]
//! take no model and write the IFC4 layout; the `*_with_owner_history`
//! variants write the model's declared release (see `owned.rs`). IFC2X3
//! declares neither `LiningToPanelOffsetX/Y` nor, on a window,
//! `LiningOffset`, and types the thicknesses as positive lengths.
