Hmm, I tried the following combination but it does not behave properly:

attrVal = xmlNodeListGetString(NULL, attr->children, 0);
xmlTextWriterWriteAttribute(writer, attr->name, attrVal);

Since "xmlNodeListGetString" and "xmlTextWriterWriteAttribute" both lead 
to a "&" to "&" conversion, I get a recursive conversion if cycling 
serialization & parsing:

"<" --> "&amp;lt;" --> "&amp;amp;lt;" --> etc.

Entity references will be mangled by xmlTextWriterWriteAttribute.
Is there any chance of adding to "xmlAttrSerializeTxtContent" (called by 
"xmlTextWriterWriteAttribute") a heuristic evaluation if a "&" is a 
beginning of an entity reference or not? But maby this does not fit in 
the big picture. Any other clues?
