Currently, setlanguageattribute is used for setting labels and descriptions. This seems confusing and inconsistent in several ways.

• the name doesn't tell us what the module does.
• it seems inconsistent to be able to change the label and description at once, but not e.g. the aliases.
• generating translatable autoComments for every combination of adding/removing/updating labels and descriptions causes massive overhead, the number of translatable messages explodes.
• the UI does not allow for labels and descriptions to be changed at once anyway. This seems to me mostly useful during item creation, which uses the setitem module.
• conceptually. there should be one API module for every operation performed on the item. Each module is the equivalent of a function.
• if and when it is desirable to update both label and description in a single edit, it's always possible to use setitem.

So, if there is no compelling reason to be able to change a label and description with a single edit without using setitem, please split these operations into separate modules. Code can still be shared by using a common base class.
