If the given element is a tag, returns which of 6 types the key attribute

- lower: The key contains only lowercase letters and underscores.
- lower_colon: The key contains only lowercase letters, underscores, and
colons.
- alpha_with_upper: The key contains only lettrs and underscores, and at
least on letter is uppercase.
- word_plus_colon: The key contains only word characters (letters,
numbers, and underscores), plus colons, but does not fit into any of the
above types.
- problem_chars: The key contains at least one problematic character, such
as a dot or a dollar sign.
- other: Anything that does not fit into the above types.
