'text-align' attribute on fo:external-graphics has a different semantics: it
aligns image (a rectangle 'content-width' x 'content-height') inside the
viewport (a rectangle 'width' x 'height'). Both rectangles coincide in your
case, so 'text-align' would have had no effect however. (But yes, XEP does
not support 'text-align' in this context :-)).

Yes, they should. To align an image wrt its surrounding fo:block,
'text-align' must be specified on the block. There's no difference with text
alignment: fo:external-image is an inline object like any character, and
should be positioned using the same rules.
