The way to centre a table is to use table-and-caption and
use the "centre contents in inline-progression direction"
directive which happens to be named "text-align=" (don't
be distracted by the name of
the property, that name applies even when aligning graphic
content inside of a content window).
There is an explicit paragraph in 6.7.2 that states the
presence of this inheritable attribute are "placed
relative to the context-rectangle...as specified by the
text-align trait". That gives credence to the
interpretation of "text-align" to be "centre contents in
the inline-progression direction".
So, in the absence of table-and-caption, the table is not
centred, but when present, the table-and-caption centres
the table. I believe
the XSL-FO 1.0 specification is quite explicit on this.
The instance below works just as expected in Antenna House
and Ibex, though I do not get the expected results from
XEP. The first test doesn't use table-and-caption, while
the other two do, the first with
an explicit specification of text-align= and the second
with an inherited specification of text-align=. Thus, the
second and third tables should be centred.

Thanks for this interesting explanatin, and for the
example. Unfortunately, FOP 0.91 beta, the FO processor I
use, seems to not support 'fo:table-and-caption'. Below the
output from FOP (stable, alpha and beta). The PDF output is
available at:
