//! XPT Version 8 implementation (not yet implemented).
//!
//! This module is a placeholder for future XPT v8 support.
//! V8 differs from V5 in several ways:
//!
//! - Variable names can be up to 32 bytes (vs 8)
//! - Labels can be up to 256 bytes (vs 40)
//! - Different header structure
//! - Different NAMESTR format
//!
//! See `README.md` in this module for more details.

// Allow dead code for placeholder implementation - these functions
// are part of the planned v8 API but not yet used.
#![allow(dead_code)]
