title: How can I comment a single line in XML?
body: <p>This rather is a verification just not to miss out.</p>
  
  <p>Is/n't there a line-comment in XML? So, one without a closer, like "//" the compiler uses.</p>
  
  <p>I saw <em><a href="https://stackoverflow.com/questions/2757396/how-do-i-comment-out-a-block-of-tags-in-xml">How do I comment out a block of tags in XML?</a></em> and several other discussions.</p>
  
  <p>This type of comment would be practical to comment out a line without bothering its closer somewhere down.</p>
