[xml/sgml-pkgs] Bug#584654: libxml2-utils: broken report when element has an impossible children element

[Marc Dequènes (Duck)]

Package: libxml2-utils
Version: 2.7.7.dfsg-2


Coin,

Using test.xml attached, and the following command:
xmllint --relaxng /usr/share/xml/docbook/schema/rng/5.0/docbookxi.rng  
--xinclude --noblanks --noout test.xml

I got:
test.xml:7: element chapter: Relax-NG validity error : Did not expect  
element chapter there
test.xml:9: element para: Relax-NG validity error : Did not expect  
element para there
test.xml:9: element para: Relax-NG validity error : Expecting element  
example, got para
test.xml:9: element para: Relax-NG validity error : Expecting element  
bridgehead, got para
test.xml:10: element filename: Relax-NG validity error : Element para  
has extra content: filename
test.xml fails to validate

which is wrong because the para element has absolutly no problem. In  
fact the 'filename' element cannot contain a 'varname' element (even  
if i don't see why DocBook authors made this restriction). So the  
error message is wrong and misleading: using a 'replaceable' element  
instead of 'varname' solves the mistake, as expected.

Regards.
