unknown attributes are silently ignored - AGWB should complain and abort
AGWB seems to silently ignore unknown attributes. One can write
<subblock name="gd_0" type="generic_detector" force_vec="0" murks="6" />
without any warning etc.
Typos go undetected this way.
AGWB should imho check the attribute lists, complain about unknown ones, and abort with exit!=0.
