Websites can easily strip away or ignore any attributes if they don’t want it. Markdown already allows adding in attributes since it allows raw html too. HTML sanitization should be kept out of the spec and left to the website. It shouldn’t be a means to prevent useful syntax into the sepc.
No it isn’t. It’s irrelevant what “they’re thinking to do with the image”, that can be handled by whatever cms/system/website they’re using stmd in.
I’m arguing that the spec should allow for a way to include attributes with the syntax proposed in 272 as it is very useful, already commonly used and much easier than resorting to html. Since if you decide later to add in an attribute to an element, you could simply append it wrapped in curly braces, without the need to rearrange the
!() part to html tag syntax.
