It's a shame that these were inherited from CSS. I can understand why
XSL should share a model with CSS, but I don't really see why it should
share this particular bit of syntax. Which rather complicates the
inheritence model as you can not (conceptually) just look up the
ancestor:: axis to find the place where the property was set. You have to
decode shorthands, each with some ad hoc syntax. (supporting this in
xmltex would be a major complication).

FO files are impossible to read in practice. When you _have_ to read
them to debug what's gone wrong (and I've been working on an FO file for
a 700 page document recently) it would probably be easier to have all
the attributes to hand rather than inherited. The thing's so big anyway
that making it bigger wouldn't harm. (I'm not against attribute
inheritence, just against that as an argument for making FO files
readable)

I agree that unifying with CSS model makes sense. Unifying with CSS
syntax (and shorthand properties are just a syntax feature) is not a
necessary consequence of that.
