alignment-baseline property

Finn, (and others of course)

what to you make out of the following?

In 7.13.2 alignment-baseline is defined as having the values: 
auto | baseline | before-edge | text-before-edge | middle | central | 
after-edge | text-after-edge | ideographic | alphabetic | hanging | 
mathematical | inherit

But further below in the text where it says "Values have the following 
meanings:" we have at the end explanations for the values:
top, bottom, text-top, and text-bottom, which according to the 
definition above are not valid values for this property.

Yes, you are correct.

So may be it was done deliberately - but I still don't understand. As 
you said its not corrected in the 1.1 draft nor is it in the 1.0 
errata.

And surely other implementers would have picked up on that long before 
me and alerted the XSL-FO WG? 

What am I not getting here?

Just thought I'd add:
7.13.1 alignment-adjust --same thing there

IIC, the definition-list should be expanded to include these latter 
four. Well, it could easily be.
Their meaning seems to be related to 'before-edge', 'after-edge', 
'text-before-edge' and 'text-after-edge', only that the ones currently 
not included in the list are only valid for horizontal writing modes 
(lr-tb and rl-tb). In vertical writing-mode they fall back to the 
dominant-baseline, as there, 'before' is 'right' and 'after' is 'left' 
--and 'top' and 'bottom' are 'end' and 'start'. If you catch the 
drift... ;-)

Not 100% sure, but this seems to be the most plausible... BTW: XSL 1.1 
also misses these in the definition --Feel like submitting the question 
to the XSL-FO WG? :-)

Cheers,

Andreas
