XSL FO Recommendation provides a means to do it:
<fo:external-image src="....."
width="100%"
content-width="scale-to-fit"/>
"Width" and "height" properties set dimensions of the viewport where the
image is placed; a special keyword "scale-to-fit" forces the respective
dimension of the image to fit the viewport size exactly. Unlike
content-width/height, percentages in the viewport dimensions
behave exactly like percentages on a block-container, and refer
to respective dimensions of the closest block area.
However: XEP 2.7x does not support it. Nor can I find any workaround. Sorry.

Not exactly. Percentages in "content-width/height" mean a scaling factor
from an intrinsic size. To denote 100% of region width, you should use
width="100%" and content-width="scale-to-fit; but, as I said, this is not
supported in the current version of XEP.
