Chris Bowditch commented on FOP-2136:
-------------------------------------

Hi Mark,

FOP is an open source project, so if you need a feature then feel free to develop a patch
and submit it for consideration by the committers

When Luis developed the table markers implementation, it was deemed too complex/difficult
to accommodate markers whose BPD could change, and it was felt that a single line value met
the most common use cases in tables, e.g. sub totals in statements

> This patch adds support for retrieve-table-marker. The patch is extensive and very likely
there is room for improvement, but it does what it is supposed to do and was tested with non
trivial examples.
> The implementation has a main constraint: the resolution of the retrieve-table-marker
element needs to be an element that does not change the BPD of the containing cell. In practical
terms this means that the height of the table header or footer where the retrieve-table-marker
element is placed cannot change once the retrieve-table-marker is replaced by the resolved
content. In the end this is not a serious constraint since in most cases the retrieve-table-marker
element is meant to be replaced by a line of text (and there is already adjacent text, or
the height of the cell is specified).
