The case is contradictory in itself, and quite unique. A nbsp will
never occur at the end of a line by its very definition, except in
this case!
Simon,
I don't quite get it what you are trying to say.
<fo:block> </fo:block>
is perfectly legal and sensible in both XSL-FO (and HTML) and doesn't
that mean a nbsp does occur at the end (and beginning) of a line.
I guess what Simon is referring to is that if the line-breaking
algorithm does its job adequately, there will be no line-break
preceding/following a non-breaking-space, except when it is the first/
last character in a block. Other break-possibilities should, in
theory at least, always be considered more favorable than breaking
before/after the nbsp... Correct, Simon?
What is contradictory or unique about this?
That indeed is a bit overstating the case. It's not contradictory,
but it is a rather special situation. Not taking into account the
number of times such a construct is used in practice... It is more of
an HTML/XSL-FO trick to make a block appear non-empty --used mainly
in the context of table-cells, to have their borders drawn despite
the fact that there is no visible content.
Cheers,
Andreas
