The array_key_exists() calls seams necessary because eg. for  
department/company i get no attributes if the isset() call is used, so  
i guess the attributes are not initialized with empty string. If you  
suspect worse performance : According to PHP bug-tracker there was a  
bug in PHP 5.1.x which lead to array_key_exists() performing much  
worse than isset(), but this should be fixed since around 2006.

For telling contacts/export which keys we want : I have seen no  
possibilty to do so without changing a lot of code in  
Turba/Kronolith/Nag. As the drop of attributes is only necessary for  
SyncML, my intention was to let it there. Maybe the clean way (extend  
the API) should be planed for Horde 4 ??
