Deeper investigation revealed that Ivy stores incorrect xml files in its cache.
In particular bug is in the method XmlModuleDescriptorWriter.write() - it does
not do any XML escaping while producing XML file. Moreover it does not check
that there are no characters that cannot appear in XML attributes, tags and so
on.
