No, it doesn't; none of those are violations of the standard given the current
values, it is perfectly acceptable to have them unquoted. It's just a bad idea.
"In certain cases, authors may specify the value of an attribute without any
quotation marks. The attribute value may only contain letters (a-z and A-Z),
digits (0-9), hyphens (ASCII decimal 45), periods (ASCII decimal 46),
underscores (ASCII decimal 95), and colons (ASCII decimal 58). We recommend
using quotation marks even when it is possible to eliminate them."
