child files not processed for validation
::::::::instructor is the right way to get instructor notes
:::::::: Instructor (Capital I) does not gives an error, but the text is then not in a box and not visible in the /instructornote.html view. It is still only visible in the "instructor view" of the course, but as normal text.
Is there a way to create error or warnings for the second div ?
Thank you for reporting this, @jcolomb! This is a feature for lessons, but in the context of child files, {pegboard} does not actually take them into account, which is clearly a bug!
I've opened https://github.com/carpentries/pegboard/issues/135 to track the issue. I will report back here when I've created a fix.
I am planning to release the fix for this tomorrow.
