As far as I know, "bill of rights" is in fact the informal name of the first 10 amendments -- which were proposed and passed as part of the political compromise that got the constitution accepted at all.
The remaining amendments are, well, just amendments. They don't necessarily specify rights, and are generally not considered part of the bill of rights.
