I understand that `startsWith("on")` precedes this PR. However, it's more 
permissive than it should be: in reality, there are only 70 global attributes 
that start with "on". On the other hand, 
`attrName.matches("data-[a-z]+(-[a-z]+)*")` is less permissive. For example, if 
I read the XML spec correctly, such an attribute can contain `_` or start with 
`data-.`.

But maybe those checks are good enough?
