Yes, I still like this syntax for block directives as well:
!!!name
content
!!!
or for that matter:
@@@name
content
@@@
with optional [label](arg){#myId .myClass key=val key2="val 2"}
like:
@@@asciiDiagram[_lovely_ cat]{ width=100 }
|\_/|
/ @ @ \
( > º < )
`>>x<<´
/ O \
@@@
Maybe separating spaces should be allowed for block directives: [] () {}
The body/content for block directives could be optional as well, so this:
@@@youtube[Funny video](dQw4w9WgXcQ)
renders as:
<figure>
<iframe width="420" height="315" src="//www.youtube.com/embed/dQw4w9WgXcQ" frameborder="0" allowfullscreen></iframe>
<figcaption>Funny video</figcaption>
</figure>
while this:
see @wikipedia[Foobar]
renders as:
<p>
see <a href="https://en.wikipedia.org/wiki/Foobar">Foobar</a>
</p>
And as @lu_zero mentioned, for simple cases attributes added to existing elements already suffice (see the proposed attribute syntax).
