Crate a2x 

Convert ALFA 1.0 source files to XACML 3.0 XML.

ALFA is the “Abbreviated Language for Authorization”, which serves as a human-friendly language for writing authorization policies, with the goal of being converted into the XML-based XACML (eXtensible Access Control Markup Language) format.

This crate attempts to implement ALFA as specified in the OASIS Working Draft 01 specification.

As this library evolves, the intent is to consider adding additional features that are planned for ALFA 2.0. There also may be deviations from the 1.0 spec, where absolutely necessary.

The ALFA 1.0 spec is ambiguous in several areas, and I have attempted to follow the observed behavior of other ALFA implementations, notably the Axiomatics “Visual Studio Code extension for ALFA” plugin.
