Handling of text-align="justify" when nesting blocks
Editors, please consider the following inconsistency in the recommendation: Example: TEST TEST TEST TEST . ENOUGH TEXT TO FORMAT INTO MULTIPLE LINES TEST ENDS A. whatever TEST TEST TEST TEST . ENOUGH TEXT TO FORMAT INTO MULTIPLE LINES TEST ENDS B. Now what would you expect: Version A: TEST TEST TEST TEST TEST ENDS A. whatever TEST TEST TEST TEST TEST ENDS B. OR Version B: (second line is justified) TEST TEST TEST TEST TEST ENDS A. whatever TEST TEST TEST TEST TEST ENDS B. Common sense would probably say "A": But, 7.15.9 of the rec says: The last (or only) line of any block, and any lines in the block ending in U+000A, will be aligned in accordance with the "text-align-last" property value. If such lines are to be justified specify "text-align-last='justify'". In the example, line 2 is neither the last nor the only line of a block, and it's also not a line ending in U+000A, so it should be justified. In contrast to this, 7.15.10 (text-align-last) says (thanks to Luca Furini for the hint): "Specifies the alignment of the last line-area child of the last block-area generated and returned by the formatting object, and to any line-area generated by the formatting object whose following sibling is a block-area that is not a line-area, and any lines in the block ending in U+000A." If 7.15.9 were worded like 7.15.10, the example would be formatted like in Version "A", which is probably what the editors intended. 7.15.9 and 7.15.10 now clearly contradict each other, IMO. My suggestion is to change the cited portion of 7.15.9 to the following wording: "The last line-area child of the last block-area generated and returned by the formatting object, and any line-area generated by the formatting object whose following sibling is a block-area that is not a line-area, and any lines in the block ending in U+000A, will be aligned in accordance with the "text-align-last" property value. If such lines are to be justified specify "text-align-last='justify'". Thanks for considering this, Arnd -- Arnd Beißner Cappelino Informationstechnologie GmbH

Thanks for digging this out. I will make a suggestion to the xsl-editors to change the wording in 7.15.9 accordingly. Thanks, Arnd -- Arnd Beißner Cappelino Informationstechnologie GmbH

Section 7.15.10 of the recommendation states that the property text-align-last "Specifies the alignment of the last line-area child of the last block-area generated and returned by the formatting object, *and to any line-area generated by the formatting object whose following sibling is a block-area that is not a line-area*, and any lines in the block ending in U+000A." So, as a fo:block generates a block-area that is not a line-area (its children are line-areas), I think line 2 should *not* be justified. Regards Luca

It sounds like you are right. This would apply to a displayed formula
in a paragraph. Nobody would want a layout in which the last line
before the display is justified, so there seems to be a problem here.

Hm, I think it's not the last line of the block. Let's see my example
again, but this time with ids:
TEST TEST TEST TEST TEST . ENOUGH TEXT TO FORMAT INTO MULTIPLE LINES
TEST ENDS A.
whatever
TEST TEST TEST TEST TEST . ENOUGH TEXT TO FORMAT INTO MULTIPLE LINES
TEST ENDS B.
The line 2 ( TEST ENDS A.) is the last line before the block "inner"
starts, but it's not the last line of the block with id "outer". The last
line of the block "outer" is: ( TEST ENDS B.).
Get my point, or am I still being unclear?
Can we safely assume the rec. means "block area" here instead of just
"block"? I think we can't, since then that would mean that the last line
on a page (or column) would also be formatted left-aligned instad of
justified even if it's not the last line of the block ("block" as in
"fo:block").
Thanks for any input,
Arnd

Hi fopdevs, if you have time, consider this: TEST TEST TEST TEST TEST . ENOUGH TEXT TO FORMAT INTO MULTIPLE LINES TEST ENDS A. whatever TEST TEST TEST TEST TEST . ENOUGH TEXT TO FORMAT INTO MULTIPLE LINES TEST ENDS B. Now what would you expect: A: TEST TEST TEST TEST TEST ENDS A. whatever TEST TEST TEST TEST TEST ENDS B. OR B: (second line is justified) TEST TEST TEST TEST TEST ENDS A. whatever TEST TEST TEST TEST TEST ENDS B. Common sense would probably say A: But, 7.15.9 of the rec says: The last (or only) line of any block, and any lines in the block ending in U+000A, will be aligned in accordance with the "text-align-last" property value. If such lines are to be justified specify "text-align-last='justify'". In the example, line 2 is neither the last nor the only line of a block, and it's also not a line ending in U+000A, so it should be justified. Right? FOP 0.20.5 does A. Any opinions? BTW: you can ignore any whitespace/linefeed-treatement issues here (all set to default): the above example formats the same with FOP if you put all of it in a single line.
