//! Build a calendar checked against the standard.
//!
//! Each property is built through the spec-driven builder, and the finished
//! calendar is validated as a whole (every component carries the properties its
//! spec requires) before it is serialized.
//!
//! Run with: `cargo run --example strict_builder`
