Also, older HTML allowed you to not quote the information after the equal sign in some circumstances.

Newer HTML too; it is only XHTML that makes quoting attribute values mandatory in all circumstances.

Since email addresses will include an @ character, the attributes are mandatory in this case.

That said, it isn't as if nobody ever breaks the rules, so it is generally a good idea to write code that can cope (unless you know that the incoming data won't have that problem).
