Dumps its contents directly into the rendered output.
This construct is not XSS safe, see: Section "unsafe-xss . "
Here for example we define a paragraph in raw HTML:
\passthrough[[
<p>Hello <b>raw</b> HTML!</p>
]]
which renders as:
Hello raw HTML!
And for an inline passthrough:
Hello \passthrough[[<b>raw</b>]] world!
which renders as:
Hellorawworld!
