Take into consideration the specification of <access> while creating the account forms.
E.g. the _UID_ field in OpenDJ has only <read> access, but it is being displayed as an input field while creating an account.
It's not working because of:
1/ schema handling support is not implemented yet while parsing resource schema
2/ <c:access> was replaced with attributeFlag element by Laszlo (if I remember correctly)
