FWIW: I think I have made sure at one point that the mapping of  
xml:lang to country/language should work (see a.o.  
org.apache.fop.fo.properties.XMLLangShorthandParser). The mapping to  
'script' is not yet implemented.
Very basically, however, since there is no validation whatsoever at  
parse-time of whether the specified value conforms to the ISO  
I see the possibility of adding this, and it doesn't even seem too  

Note that none of those properties apply to fo:root, so we'll probably  
have to assume that the natural language of the document is the one of  
the first fo:page-sequence. In theory, we always have access to the  
specified value on fo:root, but accessing that from the renderer  
context may get a bit messy (it exists only in the  
'currentPropertyList' that is available in FOTreeBuilder)
