Figure 3-4. The <ins> and <del> tags in action
3.9.1.1. The cite attribute
The
cite
attribute lets you document the reasons for the insertion or
deletion. Its value must be a URL that points to some other document
that explains the inserted/deleted text. How a browser treats
cite
is a
question for the future.
3.9.1.2. The datetime attribute
Although the reason for the change is important, knowing when a
change was made is often more important. The
datetime
attribute for
the
<ins>
and
<del>
tags takes a single value: a specially encoded date
and timestamp. The rigorous format for the
datetime
value is
YYYY-MM-
DDThh:mm:ssTZD
. The components are:
•
YYYY
is the year, such as 1998 or 2010.
•
MM
is the month; 01 for January through 12 for December.
•
DD
is the day; 01 through 31.
•
T
is a required character designating the beginning of the time
segment of the stamp.
