 To refer to XML elements (for example, your function processes specific XML elements that you want to describe in an XML documentation comment), you can use the standard quoting mechanism (`<` and `>`). To refer to generic identifiers in code reference (`cref`) elements, you can use either the escape characters (for example, `cref="List<T>"`) or braces (`cref="List{T}"`). As a special case, the compiler parses the braces as angle brackets to make the documentation comment less cumbersome to the author when referring to generic identifiers.
 
 > [!NOTE]
-> If you write comments using the single line XML comment delimiter, `///`, but don't include any tags, the compiler adds the text of those comments to the XML output file. However, the output doesn't include XML elements such as `<summary>`. Most tools that consume XML comments (including Visual Studio intellisense) don't read these comments.
