//! # tsp-ltv
//!
//! Shared timestamping (RFC 3161) and long-term validation infrastructure
//! for Advanced Electronic Signature (AdES) formats.
//!
//! This crate provides the core types and network clients for:
//! - **TSP**: RFC 3161 timestamp requests, responses, and validation
//! - **OCSP**: Online Certificate Status Protocol client (RFC 6960)
//! - **CRL**: Certificate Revocation List fetching and caching (RFC 5280)
//! - **Trust**: Certificate trust stores, chain building, and validation
//!
//! It is format-agnostic — it does not know about PDF, XML, or JSON.
//! Each AdES crate (underskrift for PAdES/CAdES, bergshamra for XAdES,
//! jades for JAdES) builds its own format-specific embedding on top
//! of these shared clients.
// Always-compiled modules
