To cite your cited ([4]) document: "Note that character references and 
references to predefined entities are considered to be expanded by the 
HTML or XML processor so that characters are represented by their 
Unicode equivalent rather than by an entity reference".

So in the above sample I expect the "root" element to simply have one 
text child node with the nodeValue " hello if A < B then ... world ". 
That is also how browsers like Mozilla or Opera or Safari implement that.
