Class names and CSS are also a source of great author confusion.

Class names as CSS selectors are somewhat confusing to authors, but in my experience less so than namespace prefixes. I think there are a few reasons: (1) indirectly binding style is less surprising to people's expectations than indirectly binding meaning/identity, since the indirection links two separate things rather than modifying meaning; (2) it's harder to make the mistake where you think the class name for actually *is* the style, than to make the mistake where you think the prefix *is* the namespace, in fact I have not heard of anyone making this particular mistake; (3) the effects of incorrect style binding are likely to be more immediately visible in the context where they are authored; (4) the binding rules of CSS are simpler and so less likely to lead to unnoticed copy/paste errors in markup.
