I presume one would also write
<p font=10pt Helvetica with 2 pt leading>Some text</p>
I'm glad HTML will express only the logical structure of a document,
and not be a formatting language. If HTML were a formatting language,
it would have to include all those nasty features that are needed to
format real documents, and people might start asking embarrassing
questions--like why invent a new formatting language when perfectly
adequate ones already exist?
