ARIA has its own spec and is not part of the DOM spec, which is what the Web::DOM namespace is for (https://www.w3.org/TR/wai-aria-1.2/). This allows us to stay closer to the spec with function names and don't have to add the word "ARIA" to identifiers constantly - the namespace now provides that clarity.
