In general, I don't think folk should be writing many if any event handlers in doc comments, and it was easier to give forward compatibility with a weak test for `"on"`. Likewise, there should not be many if any uses of `data-*` attributes, and it is easy enough to give a simple regex. It's more important to not reject valid uses of event attributes and custom data attributes than it is to detect all invalid cases. The right place to detect all invalid cases is downstream in recognized validation tools, like `tidy` which catch all occurrences of bad stuff, wherever they originate (doc comment, command-line options, the `javadoc` tool, post-processors, etc).  DocLint is primarily an "early warning system" for common errors.

Sure, I will go with that.
