[xmlroff] XSL-FO question

[Steve C. <g3c...@cd...>]

This is really a general question about the XSL-FO spec,
but since Tony Graham is listed as a contributor there
maybe I can coax him into answering here :)

How are property value specifications supposed to be
parsed in XSL-FO?  One place it says that they
can be "expressions" (e.g. "from-parent()" etc.),
but in list of properties you often have something
like this (for font-family):

[[ <family-name> | <generic-family> ],]* [<family-name> | <generic-family>] | inherit

which seems to be incompatible with the expression
grammar.  Is the whole thing taken as a string,
and therefore one is forced to write:

font-family="'Verdana, Arial, ...'"

(note the double-quoting) which seems very awkward
and certainly not how CSS is written.
If not, how would one use expressions in the font-family
specification?
