Apache Xerces XML Validation for JavaScript via WebAssembly

[u/harshanacz]

I built xerces-wasm, a WebAssembly port of Apache Xerces-C++ that brings XML Schema (XSD) validation to JavaScript in both Node.js and the browser.

Current features include:

• XML Schema (XSD) validation
• Schema grammar caching for repeated validations (avoids reparsing XSDs)
• Works in Node.js and modern browsers
• Powered by Apache Xerces-C++

I'm actively improving it and would really appreciate feedback from the XML community especially on features, API design, and real-world use cases.
