KDE KAddressBook has <x-crypto><allowed> to select which kind of email encryptions are allowed for the contact.

foreach ($item as &$subItem) {

Has an issue because $subItem is an array:

$item = array (
  0 => 
  array (
    'name' => '{urn:ietf:params:xml:ns:vcard-4.0}text',
    'value' => 'PGP/INLINE',
    'attributes' => 
    array (
    ),
  ),
  1 => 
  array (
    'name' => '{urn:ietf:params:xml:ns:vcard-4.0}text',
    'value' => 'PGP/MIME',
    'attributes' => 
    array (
    ),
  ),
  2 => 
  array (
    'name' => '{urn:ietf:params:xml:ns:vcard-4.0}text',
    'value' => 'S/MIME',
    'attributes' => 
    array (
    ),
  ),
  3 => 
  array (

Above commit is an idea of me to solve this for my needs.
I have no idea if this is the correct "hack" way for this library.
