Comments in XML

• Comments in XML have the same syntax as HTML comments:

  <!-- This is a comment -->

• The string "--" may not appear within a comment. The following is illegal:

  <!-- This is a -- comment -->

• A comment may not be nested within another comment.

• Comments may appear anywhere in a document, except within other markup. The following, for example, is illegal:

  <book used="no" <!-- this book is new --> language="english">
