Characteristics:

• The <b:comment> tag works in all of the XML, except in the tag <b:skin>.
• Several <b:comment> tags can be combined.

Attributes used:

At first glance, this tag can make you smile, but it is very useful because, not only does it allow you to add comments, but in addition, it executes the Blogger expressions that are in the comment.

And since that was not enough, we can also add attributes that are listed under.
