The text written in small-caps never applies to a full line. It's two or three words, sometimes a little more. Anyway the use of "first line" does not seem very convenient for a flowing ePub... You can get strange results.

Before leaving this thread, I noted that using a double span to control the display of a drop-cap is more flexible and precise than using a single one. I do not say that it is impossible to do it with a single span, just that it's more difficult and fragile.
