# Configuration options:
# * <tt>:on</tt> - Specifies when this validation is active
# (<tt>:create</tt> or <tt>:update</tt>
# * <tt>:if</tt> - Specifies a method, proc or string to call to determine
# if the validation should occur (e.g. <tt>:if => :allow_validation</tt>,
# or <tt>:if => Proc.new { |user| user.signup_step > 2 }</tt>). The method,
# proc or string should return or evaluate to a true or false value.
# * <tt>:unless</tt> - Specifies a method, proc or string to call to determine
# if the validation should not occur (e.g. <tt>:unless => :skip_validation</tt>,
# or <tt>:unless => Proc.new { |user| user.signup_step <= 2 }</tt>). The method,
# proc or string should return or evaluate to a true or false value.
# * <tt>:strict</tt> - Specifies whether validation should be strict.
# See <tt>ActiveModel::Validation#validates!</tt> for more information.
# If you pass any additional configuration options, they will be passed
# to the class and available as <tt>options</tt>:
