Syntax idea: Section "tags"/margin notes

[ptgolden]

It would be nice to be able to "tag" certain sections with indexing terms.

This could go some way towards approximating something like Archie Markup Language.

Here's an example. Say I'm taking reading notes, and I want to bookmark some places where regulation and networking are mentioned. I stick in a tag that will be inserted in the point of the document where I discuss these things

::: tag regulation, networking :::

p. 2: notes that "unremitting political intervention was necessary" to secure 
free-market regime in computing policy. Progress in this goal was both political 
and economic.

This way, we could expose something in the interface that would enable someone to say "show me all the places in my notes where I tagged regulation or networking". Potentially, tags could be topics also, in the @@t{id} syntax.

An alternative would be to have some syntax that would be hierarchical- a tag refers not to a single point in the document, but to a range. I think that might be a little more complex than needed.

This is akin to the kind of margin notes you see in textbooks or the bible, where margin notes indicate the presence of key concepts or themes, allowing for skimmable reference.

So tags would apply to everything in the note until 1) the next tag or 2) the end of the note? Or would they be more like anchors, just points within the note rather than specifying sections/ranges?

What I was suggesting was anchors in text. The "alternative syntax" idea I referred to would cover spans of things. However, I think it might be better to have headings handle the job of sectioning things.
