Certain tokens should be treated as text outside of attribute context.

[Jakub21]

In the following example,

$div {
    Hello world!
}

The exclamation mark is treated as a special operator. Exclamation marks are used for quick flags, only relevant when inside node attributes $div[!here]. Quick flag operators outside of the attribute context must be treated as text. Other tokens might have to be changed as well, maybe =?

Result (missing exclamation mark, currently requires /! to appear)

<div>
Hello world
</div>
