    Bug Description: 99user.ldif getting overpopulated
    Reviewed by: self
    Branch: HEAD
    Fix Description: The schema code was adding X-ORIGIN 'user defined' to all
    schema elements that had no X-ORIGIN.  It should only add user defined to
    schema elements from the user defined schema file, not to schema defined
    in standard (read only) schema files.  It looks like the code should work
    fine if the schema element has no origin, so there is no reason to add
    an origin for schema other than user defined schema.
    Platforms tested: RHEL5 x86_64
