Well here's the thing I guess. I think it is a significant
ommision that the FOP spec fails to supported paper that can
be folded, even if this sort of paper is no longer in vogue.
Still this is the case in point.
Now if I were in the business of making W3C recommendations
(i.e teaching my grandmother to suck eggs) I migght (at this
juncture in my infant learning curve) suggest
1) deprecating
<[fo:]page-number/>
in favour of
<[fo:]page-pseudo-number/>
or
<[fo:]page-not-really-a-number-just-pretending/>
2) reworking <[fo:]page-number/> to return (I don't know, maybe)
a _number_.
3) introduce fo:column-number, span-number, flow-number and
wing-number (which would all return _numbers_) - the latter
being most useful in annotating paper planes.
4) introducing
<[fo:]page-number-enhanced/>
which would include the more common use atrributes like
linear-function-to apply_to_number="2x-1"
<!-- for linear transformations - default = x -->
base-of-numeric-system="5"
<!-- for other numeber systems" default = 10 -->
angle-in-degrees-to rotate-number-by="90"
<!-- for people who read in bed -->
(Notice I have correctly avoided any hint of "terseness" in my
naming conventions.)
Can anyone think of any other useful enhancements?
Well I guess its back to the drawing board for now.
WPE (tongue in cheek)
P.S
How may FOP programmers does it take to change a lightbulb?
Only one, however please note that <fo:light-bulb> does not
actually return any light, but does a neat light shade.
