# TEST

Executing kramdown results in:

$ kramdown test.md   > test.html
Warning: No or invalid attributes found in IAL/ALD content:

forgot to mention: This was no problem in kramdown 0.14.2.

Thanks for reporting! There should definitely not be a warning in this case.

This is low priority - No real rush or urgency from my side. I also forgot to say thank you for all your efforts and for this wonderful gem!! Danke.

Warning: No or invalid attributes found in IAL/ALD content: 

(Users of kramdown-rfc2629 get this around five times for every invocation…)
