images without alt should not generate alt attribute with empty string about micromark

[wooorm]

I don't know if this is really a bad thing, but the new behaviour of micromark is to generate an empty string for the alt attribute, where as the old remark-parser used to set the alt property of the mdast node to null.

Correct, this was not in old remark. This was raised on twitter a bit ago to me: having the empty alt instead of no alt thus is also practical, for accessibility, and not just theoretical. And I checked: it’s commonmark compliant to use an empty alt attribute.

not sure. But for backward compatibility's sake: A markdown image w/o an alt text should not create an alt attribute in HTML (mdast node's property should be null)

Following commonmark is more important to me than backwards compat.
