Invalid Contact References

Nic handles of person or role objects should consist of letters, numbers and '-'. References to person/role objects not complying this convention should not exist, since it probably points to an invalid person/role object. The most typical examples are references by phone, name, or e-mail address instead of a nic handle.

Example:

In the following example, John Smith is an invalid contact.
