DV>   No. It just mean that the xmlSetProp API has that characteristic.

 But since xmlSetProp() doesn't handle entities by itself, what will
be correct way of setting attribute value with handling embedded
entities? Should it be something like xmlNodeSetContentLen() ?

 No, i don't use Perl for myself, it was just an example, posted in a
forum as response for my question. However same example with libxml2
v2.4.19 produces same output.

 No, I don't want to go so far, i just want to be sure that authors of
PHP bindings will be able to implement proper bindings for your
library. For now i get almost all necessary information to be able to
point them on it.

 Yes, i've checked your API already, thank you for information.
