Re: [asciidoc-lang-dev] Markup for nested blocks

Understood. Fair point.

I agree that trying to assert the outcome of invalid markup is not necessary and would bog down the spec and TCK. Particularly with a lightweight markup, there will always be some creative way to get it to produce invalid markup. We should focus on what is correct syntax and ensure that all implementations interpret it correctly. If we do add negative assertions, they should be selected strategically.

Asciidoctor followed on this and allows nested markup where the rx-based substitutor could handle it. For example and And those are critical to support*. However, Asciidoctor has never supported partially overlapping markup since it's invalid in XML/HTML anyway. There's no definitive statement, but it's well understood by the community of users.

Best Regards,


* The inline parser may free us from having to worry about the nesting order. The limitation is a constraint of the rx-based substitutor.
