Needed: formal DBML spec

[MFornander]

Thanks for the new Lineage feature!

I am looking for a formal machine readable .dbml spec such as EBNF/PEG/JSON-Schema spec. This would help to see these new changes in one place, to understand how the spec is versioned and backwards compatible, and also to see the exact syntax so we can use formal parting tools which is more an more important now that dbml is evolving.

Did I miss something?

Went ahead with some preliminary spike work guided by:

"Goal: give DBML (holistics/dbml) an authoritative formal specification, enforced by conformance tests against the reference parser, without changing how @dbml/parse or @dbml/core behave. Target: a series of small upstream PRs."

Let me know if this direction would be compatible with your vision and roadmap.
