HTML 4.01: Erratium

Hello, guys.
I want to write about 3.2.2 Attributes<http://www.w3.org/TR/html401/intro/sgmltut.html#h-3.2.2> section of HTML 4.01 Specification.
I am not sure whether it is wrong or not, but still...
This section specify that the only legal characters for attribute values are "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)", meanwhile later in specification I can see that value of some attributes (e.g. style) can contain semicolons (ASCII decimal 59).
So could you please clarify whether semicolon is a legal character or not?

Thank you in advance.

Best Regards
