Originally created by @aKzenT on GitHub (Sep 19, 2016).

For our project, I'm writing an extension which sets custom attributes on some Markdown Elements, which should be rendered in the resulting HTML (e.g. for styling).

This works fine for almost all elements (paragraphs, lists, etc.), but fails for the definition list extension, because it will always write an empty

element without honoring any attributes set on the description paragraph.

There is also currently no good workarround for this issue. I would currently need to copy the complete extension only to change this single part.

Best regards,
Thomas

Hm weird, the code here and there does write the attributes. Could you elaborate how do you add these attributes?

It't the
renderer.Write("<dd>");
that's causing the problem for me.
