I just ran into this problem trying to insert some SVG graphics into my document, rendered by FOP. The graphics were big, and were not scaled to fit on the page.

I manually edited the FO to change content-height and content-width to "scale-to-fit". Unfortunately FOP (0.20.5rc) does not seem able to handle this:

[ERROR] Error in content-width property value 'scale-to-fit': org.apache.fop.fo.expr.PropertyException: No conversion defined
[ERROR] Error in content-height property value 'scale-to-fit': org.apache.fop.fo.expr.PropertyException: No conversion defined

This seems to be a known limitation in FOP, which in turn may be why the stylesheets don't use this attribute by default.
