Lists with inline and superscript
Hi,
I just discovered (?) a issue in the list-block containing inline with
vertical-align. The output shows <fo:list-item-label> and
<fo:list-item-body> "putted out of line" (i'm not sure if this is the
correct verb, sorry!!). I just checked with the list.fo example and the
problem persists.
You can see what i mean in this pdf
http://www.nabble.com/file/3993/listinline.pdf listinline.pdf
Here is the fo:

Try using line-stacking-strategy="font-height" on the list-item. That
won't make the baseline dependant on the content.
BTW, you've got a bug in your example FO file: page-height="29,7cm" must
be page-height="29.7cm". See FOP's warning on the log.

Hi Manuel,
Thanks for your response, i undertand what you mean.
I'm a bit dissapointed because if i use subscript the line-height seems to
be correct between item-label and item-body. Bad news because i'm forced to
use superscript.
If you'll think some solution to override this issue, please let me know.
Cheers.

Thank you for the example pdf and fo file.
After checking what the spec says about lists I believe fop is doing the
right thing. Because in XSL-FO the list-item-label and the
list-item-body elements create independent areas, that is they are
defined using separate fo-block elements, there is no concept of a
common baseline between those blocks. Because defining a
superscript/subscript changes the line height for the block (you can
see that more easily by giving all your blocks borders) and the
position of the baseline, the labels are not anymore aligned with the
list bodies. You can get the same effect by simply giving the label
blocks different font sizes to the body blocks.
Not sure if there is a workaround available for this in the current fop
version. XSL-FO defines the line-height-shift-adjustment property for
such cases. This property controls line-height and baseline position
changes in the presence of sub/superscripts. Unfortunately we don't
support that property and your case is the first I came across on this
list which would benefit from this property.
