# Custom Attributes (C++)
A custom attribute is a strongly typed technique that allows the user to extend metadata. This topic deals with using attributes: specifying parameters and targets.  
  
 For information on defining new custom attributes, see,  
  
-   [User-Defined Attributes](../windows/user-defined-attributes-cpp-component-extensions.md)  
  
-   [attribute](../windows/attribute.md) (deprecated syntax).
