Should revisit <! {! because of raw tags and custom attribute clash

[Ducasse]

Contexte

In Microdown
{! is for extension in paragraph and <! for new block extension.

Problem one custom attributes

Now { is used for custom attributes.

# CSS Classes{.WARNING}
Using `.css-class` syntax lets you apply custom CSS classes.

## Id Values{#Updates}
Using `#id` lets you apply custom ID values.

## Custom Styling{style="color:darkgoldenrod"}
For everything else you can use attributes

Solutions for custom attributes

• Sol1. Introduce a new token % for example? for custom attribute introduction - would prefer to be compatible
• Sol2. Replace {! by something else for example !{ }!

Problem two: support for raw paragraph

raw paragraph starts with < and conflicts with <!

<iframe>
...
</iframe>

Solution for raw paragraph clash

• change <!inputFile|path=file!> into another token.
• Candidate could be [!inputFile|path=file!]
