20//! # UNIC — UCD — Identifier Properties
21//!
22//! A component of [`unic`: Unicode and Internationalization Crates for Rust](/unic/).
23//!
24//! Accessor to the UCD properties used widely by [UAX31 Unicode Identifier and Pattern Syntax].
25//!
26//! # Features
27//!
28//! - `xid` (default): the `XID_Start` and `XID_Continue` properties.
29//!
30//! - `id` (optional): the `ID_Start` and `ID_Continue` properties.
31//!   NOTE: in most cases, you should prefer using the `XID` properties
32//!   because they are consistent under NFKC normalization.
33//!
34//! - `pattern` (optional): the `Pattern_Syntax` and `Pattern_White_Space` properties.
