Comments
You can leave notes within an XML document in the form of a comment. Comments begin with <!--
and end with -->
. If you’ve used comments
in HTML, this syntax should be familiar. The example document contains the comment:
<!-- more customers will be added soon -->
Comments are not elements and, therefore, do not affect the structure of the document. They may be placed anywhere in a document except before an XML declaration or within a tag or another comment.
