It seems to work as desired only with ' from="root|section" '.

While this works for xsltproc (compiled against libxml 20626, libxslt 10117
and libexslt 813) it does not work for xalan-j_2_7_0 -- is that an xalan
bug?

You can handle that by extending the from condition, for example

from="level1|section".
