textarea: attribute for content type

The user agents, bots, and scripts know nothing of the content of the textarea and cannot provide syntax highlighting or input validation.

The textarea element does convey semantics as to what the content is other than its natural language via the lang attribute.

None, but you can use your own custom data- attributes but then there is no standard for it and it only works with your scripts.

You can use JavaScript libraries such as Ace, CodeMirror or Monaco if you want a nice experience but the markup has no semantics.

Add a attribute to to the textarea element.

Example:

<textarea enctype="application/json">{}</textarea>

or:

<textarea codelang="python">fruits = ["apple", "banana", "orange"]</textarea>
