i think this is wrong. we dont pass any name hint and thus our names would be generated as `jcr:` which is defined but something we should not use for our nodes.

from how i read the code, the trick would be to pass `''` as 4th parameter, then the defaultNamespace is ignored. this is probably a bug, it should be possible to pass null as defaultNamespace.

could we map the name hint with the id configuration as well? then one could also generate names that start with some prefix.
