As a designer, I think there’s a better way of handling it than having double punctuation. I will get nowhere with this particular client. But are most punctuation guides pretty comprehensive? Meaning, that if they list examples, can one assume that any other uses are incorrect, and that if emphasis or pausing is needed, that it should be dealt with some other way?

Sorry, the url kept getting truncated. Add the above to replace the ellipses in my two posts.
