    Resolution: Not A Problem

The two overflow messages can be explained:
* Regarding the region-before:
height doesn't apply on fo:block, so it is just ignored. A value of 100% on the 
external-graphics means that it takes its height from the parent element (the 
fo:block). But since the size of that latter depends on its content, the value 
is interpreted as "auto" (see Section 7.15.6, "height", from XSL-FO 1.1).

On an external-graphic, a value of "auto" for height means that the intrinsic 
size of the graphic is used (see Section 6.6.5, "fo:external-graphic", from 
XSL-FO 1.1).

Basically, you cannot use percentages to specify the height of an image. You 
have to put the size explicitly (from which you have subtracted the border 

* Regarding region-body:
The height of 100% set on the block-container specifies its /content/ height: 
just the content, without the padding nor the border. But since you specified a 
border of 0.25mm, that doesn't fit in the page. Set the height to "100% - 
0.5mm" and the overflow error disappears.
