I basically want to distinguish two different data sources, after parsing  
them as XML and merging them, so I thought it was possible to use entities  
in one of them explicitly, and the other not.

I see now that it's ONLY &amp; that is kept as-is. I was falsely under the  
impression that named entities was handled different from numeric  
entities, but I see now that this is not the case. Hence my original issue  
with lack of consistency is invalid.

$ perl -wle 'use XML::LibXML; my $x = XML::LibXML->new(); my $d =  
$x->parse_string("<xml>&apos; &#39; \x27</xml>"); print $d->toString();'
<?xml version="1.0"?>
<xml>' ' '</xml>

Thanks for the info everyone and sorry for your waste of time ;-)
