  Key Concepts: 
  A tag library descriptor (TLD) is an XML document that describes a tag library. It is used by the JavaServer Pages (JSP) engine to validate the tags used in a JSP page. The TLD contains information about the tag library, such as the tag names, attributes, and functions. It also contains information about the tag library's implementation, such as the class name and method name of the tag handler. 
  
  How to use it: 
  The TLD is used by the JSP engine to validate the tags used in a JSP page. The TLD contains information about the tag library, such as the tag names, attributes, and functions. It also contains information about the tag library's implementation, such as the class name and method name of the tag handler. The TLD is referenced in a JSP page using a  directive. 
  
  Tips & Tricks: 
  When creating a TLD, make sure to include all of the necessary information about your tag library. This includes the tag names, attributes, functions, and implementation details. Also make sure to reference your TLD in your JSP page using a  directive.
