https://issues.apache.org/bugzilla/show_bug.cgi?id=51639 --- Comment #3 from Vincent Hennebert 2011-10-05 17:26:10 UTC --- (In reply to comment #2) Hi Alexey, I'm not too familiar with inline-level layout but, yes, its does indeed seem like what we want is to get the height of KnuthGlue instances in addition to KnuthInlineBox. I suppose AlignmentContext instances would be passed the same way as for KnuthInlineBox. There may be undesirable side effects I can't think of right now. Obviously this would have to be made only for KnuthGlue instances that are actually derived from white space characters.

Re: omit first table header/last footer
It seems although it does happen.. there are some work arounds this. 1) Setting line height and height to 0mm this includes that of any inline objects however within inline objects the content height does not effect 2) the location of any parent for-each statement. if specified within the table body the error occurs, if specified within a block all works ok. I shall continue to try and diagnose where errors occur. Maybe if I can find the cause somebody can modify to fix. Unfortunately I am by no means competent to look at code to do the same.

I agree that implementing retrieve-table-marker is not only a more generic solution but also what the spec requires. However, I'm short on time and this seems easier so I'll give it a try first.
