Could you build this?

Partial Writing a generic parser generator grammar can be vibe-coded, but fully implementing the complex ISO 10303 EXPRESS formal data modeling specification requires deep parsing and domain expertise.

What it would actually take: The project requires using an ANTLR, Tree-sitter, or LALR parser generator in C/Rust/Python to implement the complete grammar specified in ISO 10303-11. The hard part is supporting the intricate constraints, procedural algorithms, schema interfaces, and edge cases of the 40-year-old EXPRESS standard. A compiler/formal grammar specialist is needed to validate compliance against industrial STEP schema test suites.
