Does not work in ADE. So if your ePub is going to eventually be used with ADE, you'll have to do it another way which is to change the font size to 75% and use caps in the text unless you are embedding fonts and you can then use a smallcap font.

That becomes a code mess if you haved MIXED CASE SMALL-CAPS.

Unless the small-caps are critical, I prefer leaving the font-variant and hoping it will be supported at some point in the future. ADE supports hyphenation and ligatures now, so maybe it's not a lost cause.

It is a required part of the spec. text-transform is not, though.
