"The beginning of the tag does not close" when commenting inside the tag of the beginning and end of the XML element

Question

<!-- Comment --> is a way to add comments to an XML file. Does this not mean that this part is not "compiled"?

However, when I do something like this:

 <item android:id="@+id/ss3" android:icon="@drawable/some_icon" android:title="Blabla Title" tools:ignore="AppCompatResource" <!-- --> /> 

I get the error message "The start of the tag does not close." Why?

Answer 1

Comments are not allowed inside tags. You must first close the ">" or "/"> tag and then add your comment.
