Response from the Working Group
================================
G164 states that the cancellation procedure does not have to be
online. There may be valid reasons why a legal signature is required
or identity must be verified by phone before a transaction can be
canceled. It is, however, best if the cancellation procedure is
online. G164 has been modified to clarify that an online cancellation
procedure is best but that phoning customer support can be a valid
mechanism in order to be "reversible" per success criterion 3.3.4.

The new text is:

After submitting the form, the user is informed of the length of the
cancellation period and the procedure for canceling the transaction.
It's best to provide the cancellation procedure at the same website
where the transaction was submitted so that it is as easy to cancel as
it was to submit and to accommodate users who may be unable to use
other mechanisms. But, if necessary, the cancellation procedure may be
provided through some other mechanism or combination of mechanisms as
long as it has equivalent cross-disability accessibility. In this
case, users are warned prior to submitting the form that they will not
be able to cancel their order online.
