HWL>     font-style: italic;
HWL>   }

If Headline is not installed locally, what is the computed value of the
font-family property?

On this content

<h1>Some <b>bold</b> statement</h1>

what is the font-family for the b element?

I wasn't there to present your proposal. I was there to show that W3C
listens to and is aware of the needs of font designers and
typographically aware content designers.
