I'm not quite sure what you're trying to express, here.

.className or #id

but not

#id.className

An id, class, or pseudo-class selector can appear by itself [optionally
combined with an element], but more than one type of attribute selector
cannot be combined.

Or perhaps:

#id.className

but not

.class1.class2

Multiple attribute selector types can be used together, but only one of
each type can be used at once.

As I read it, the grammar permits the latter, but it also places very
tight constraints on the /order/ of simple selector components: element,
id, class, pseudo-class. A simple selector can contain any of these, but
if any are present, they must appear in that order and can only occur
once at most.

The reason why

.subsubsection#sverige a

fails is because the id selector follows the class name.

#sverige.subsubsection a

will be accepted.

Note that the W3C validator doesn't care much for the order, either
because it wasn't meant to be significant (but that fact couldn't be
expressed concisely in the grammar), or due to a bug.
