How to enabling "safe html" in the description textarea of the validating-string-parameter-plugin?

[martinda]

The textarea for the description of the String Parameter supports HTML.
How do I modify the code in the validating-string-parameter-plugin to obtain the same HTML support in the plugin description textarea?
My attempt is not successful:

Can someone help?

Thanks,

Thanks to danielbeck, the part I was missing was to use the codemirror-mode:
<f:textarea name="parameter.description"
value="${instance.description}"
codemirror-mode="${app.markupFormatter.codeMirrorMode}"
codemirror-config="${app.markupFormatter.codeMirrorConfig}"
previewEndpoint="/markupFormatter/previewDescription" />
