Granted...
Question in this particular case, however, is what the stylesheet authors hope
to achieve by adding  'span="inherit"' anyway. The property only has effect for
areas returned by a flow-child. Although the property is not inherited, further
descendants automatically take on the characteristics of their parent (see:
http://www.w3.org/TR/xsl/#span)

I think the reason behind the warning is indeed stylesheet debugging, in the
sense that one would expect a value on the parent for a specified value of
'inherit' on the child (?)

The keyword is permitted as a value for inherited properties, but hardly useful
there...
If used for non-inherited properties, then it should indeed evaluate to the
computed value.

The explicit value obtained in PropertyMaker is used /only/ to check whether
there was a value specified on the parent. If this is not the case, then the
computed value will evaluate to the initial value, and so could just as well
have been omitted...

All the same for me to have FOP shut up in those cases, or reduce it to
debug-level.
