XPath, XQuery, and XSLT for Rust

Pronounced "crust".

The goal of this project is to implement XPath 3.1, XQuery and XSLT 3.0 in Rust.

Currently the project is a proof-of-concept. There is a rudimentary implementation of the XQuery and XPath Data Model 3.1, along with an implementation of XPath which, roughly speaking, conforms to version 1.0 (with a few other features, such as FLWR expressions).

Design

The library separates parsing from evaluation.

The Plan

1. An XQuery processor.
2. An XSLT processor, implementing approximately v1.0 functionality.
3. Improve XDM, XPath.
4. Introduce all v3.0 features to the XSLT engine.

Compliance

Status of docs/compliance.md with XDM, XPath, XQuery, and XSLT.
