[xep-support] Font configuration feature request

[Werner Donné]

Dear,

I think it should be possible to configure an alias name that maps
to a list of fonts, just like the value of the font-family property.
This would make it possible to also use symbolic names, such as
"serif", "sans-serif", etc., for PostScript fonts. You always need
several font files if you want to cover a reasonable portion of
Unicode.

Now, all those fonts must be listed in a font-family property of the
document instance. This creates a tie between the document instances
and the font configuration, while the latter should be able to evolve
without affecting the application that produces the XSL-FO instances.

It is possible to do this by letting the font attribute of the alias
element have a list such as for the font-family property. XEP can
easily expand it to one list before creating its font data structure.
By the way, I didn't find anything about alias elements that reside
directly under the fonts document element in section 5 of the userguide.

Another option is to allow that several font elements have an alias
element with the same name.

Regards,

Werner.
