We had the same issue for our (php.net and pear.php.net)
documentations (written in Docbook5).
We use "shitloads" of entities for various things and "suddenly" got
thousends of "namespace default prefix was not found" errors as of
libxml2.7.4 (or was it .5 maybe?).

Although I do understand the logic be behind it (see bug#502960), it
caused us great deal of problems and not something I expected from a
bugfix release :|
To late to do anything about it now, long after the release :(
