I'd like to better understand these two HTML5 content models. They don't really seem to offer anything.
Isn't Flow the same as HTML4 inline? What like just stick with the name inline?
As for Sectioning, (article, aside, nav, section), why does that matter? If I want to create a section, I'll use that tag. When I use article, aside, and nav, I'm not thinking of sections (because there is a section tag for that). I'm focused on independent content, tangential content and navigation. How does knowing that these are sectioning tags help a developer or offer any benefit?
