Spec reference please - I don't think it is possible to say for certain
either way.

The reason I think you are wrong is because given
P.note:before { content: "Note: "; display: marker}
P.note        { border: solid green }

the border doesn't cover the marker box (the spec is very explicit on
this), so there is certainly is an indication that this result is
possible at least for some generated content.

In addition, it tends to give better results - you cannot set the
margins of the anonymous block with the interpretation that you take. 

Some normative statement would be nice though...
