No, people use it sloppily where there is only one repeat. >BTW, where does the 1.6 standard explicitly forbid this final :|?

This would imply that >the above notation is legal, since that bar line *is* the end of a >repeated section. You are quite right. I could have sworn that the standard forbade the use of :| to terminate the second repeat. Maybe it was in an earlier version of the standard?
