I'm listed as a contributor for my work on the XSL 1.0 test suite when
the XSL spec was a Candidate Recommendation. I am no longer on the
W3C XSL FO subgroup.
Questions like this should go to the xsl...@w3... list.

But the text after the box for font-family says:
<string>
The names are syntatically expressed as strings.
I would say that since the property is taken from CSS, it should be
parsed like CSS2, but I don't speak for the XSL FO subgroup.
There is, of course, the counter-example of <uri-specification> which
in XSL requires more quoting than most people expect.

Tony.
