You might try "font-style oblique;" as that is perhaps more likely computed anyway. My CSS book is mostly for browsers, but it might be allowed in ADE.
Edit:
For ADE, using a fall-back generic seems to work OK - from this span class:
.TurinTalk {
font-family: "Hand Me Down S (BRK)", sans-serif;
font-style: italic;
}
I do get italic sans-serif text...
from this:
.subvocal {
font-family: "Hand Me Down S (BRK)", sans-serif;
}
I get the hand-me-down font used.
So try a fall-back in the class definition -not in the @font-face definition, as you may recall
