* Let xml.sax initialize pyexpat-backed parsers RustPython already exposes an Expat-like XML parser, but xml.sax expects a few setup APIs before parsing. Add compatible parser setup methods and constants without pretending to implement full Expat external entity behavior. Constraint: Lib/test changes only remove expectedFailure markers for tests that now pass; test bodies and assertions are unchanged. Rejected: Implementing full Expat parameter entity parsing | xml-rs does not expose that configuration and the immediate failure is the missing setup API. Confidence: high Scope-risk: narrow Directive: Keep SetParamEntityParsing as a compatibility shim unless the backend grows real Expat-style entity parsing support.

Standard Library for RustPython
This directory contains all of the Python files that make up the standard library for RustPython.
Most of these files are copied over from the CPython repository (the 3.7 branch), with slight modifications to allow them to work under RustPython. The current goal is to complete the standard library with as few modifications as possible. Current modifications are just temporary workarounds for bugs/missing feature within the RustPython implementation.
The first big module we are targeting is unittest, so we can leverage the
CPython test suite.
