[libxml++] Const correctness of write_to_...

[<Loi...@re...>]

Hello,

Is there any reason why the xmlpp::Document::write_to_... functions are =
not const ? I have a const refrence to an object that contains a =
xmlpp::Document, and I have to use ugly const_cast to be able to do what =
seems to me to be a non-modifying operation.

Regards,
