This looks great! I share your sentiment: I looked into the XML files for the published German legal texts[1], and they seem to be made for display purposes only.

I actually pitched to the American Society of Quality Assurance a few years ago that we should be going to the various governing jurisdictions with a schema and encourage them to publish regulations in a standard format.
The benefits of treating regulations as data are enormous - not only do you have a standard way of consuming and linking regulatory requirements like in an API, you also get discoverability, the ability to make tools (syntax highlighting in legalese!), compile requirements over multiple jurisdictions, and more!
I had difficulty selling the idea among the non-computer-savvy (but technical) regulatory professionals, but I'm sure a few of you on HN can imagine the benefits of having a tree-sitter for legal code...
I could have pushed it further, taking the lead to pitch to the various regulators I work with in my consulting business, but in the end it was just too much work for a side project without interest from my peers.
Could be a https://xkcd.com/793/ situation though.
While the programmer/engineer in me likes the idea of trying to codify and constrain standard legal terms and grammar to some consistent interpretation, I do think this is an XKCD style oversimplification of a very complex system.
Though IANAL I am a "regulatory QA professional" who has to interpret intent, wording and current enforcement of various food, drug and cannabis regulations every day. It's a complete mess of spaghetti code and undefined behaviour, and worse it's the implied, imprecise and badly worded parts that turn out to be the most important.
It's a moving target of guidance documents, published inspection findings that reveal "the current thinking of the inspectorate" and "industry best practices" with no single point of reference. Not to mention the pharmacopoeia and published standards. Though there are so many ways we could improve things, I doubt you could ever actually get that ideal constrained language without turning it into a billion special cases.
It can be very frustrating to work with, especially trying to convince management why they can't do something that isn't expressly forbidden in the regulations! But this does show exactly why there's so much leaning on intent rather than precise requirements - much like tax code, organisations would and do find money-saving loopholes all the time that might put people at risk, hence the moving target of interpretation and best practices.
This! I think this would enable so many services that make the legal system more approachable for many people.
