public @interface FacesComponent
```
The presence of this annotation on a class that extends UIComponent must cause the runtime to register this class as a component suitable for inclusion in a view. If the createTag attribute is true, the runtime must create a corresponding Facelet tag handler according to the rules specified in the attributes of this annotation.

Modifier and Type	Optional Element and Description
`boolean`	`createTag` If the value of this attribute is `true`, the runtime must create a Facelet tag handler, that extends from `ComponentHandler`, suitable for use in pages under the tag library with namespace given by the value of the `namespace()` attribute.
`java.lang.String`	`namespace` If the value of the `createTag()` attribute is `true`, the value of this attribute is taken to be the tag library namespace into which this component is placed.
`java.lang.String`	`tagName` If the value of the `createTag()` attribute is `true`, the runtime must use this value as the tag name for including an instance of the component annotated with this annotation in a view.
`java.lang.String`	`value` The value of this annotation attribute is taken to be the component-type with which instances of this class of component can be instantiated by calling `Application.createComponent(java.lang.String)`.

  - value
```
public abstract java.lang.String value
```
    The value of this annotation attribute is taken to be the component-type with which instances of this class of component can be instantiated by calling Application.createComponent(java.lang.String). If no value is specified, or the value is null, the value is taken to be the return of calling getSimpleName on the class to which this annotation is attached and lowercasing the first character. If more than one component with this derived name is found, the results are undefined.
    
    Returns:
    
    the component type.
    
    Default:
    
    ""
- - createTag
```
public abstract boolean createTag
```
    If the value of this attribute is true, the runtime must create a Facelet tag handler, that extends from ComponentHandler, suitable for use in pages under the tag library with namespace given by the value of the namespace() attribute.
    
    Returns:
    
    true to create the Facelet tag handler, false otherwise.
    
    Default:
    
    false
- - tagName
```
public abstract java.lang.String tagName
```
    If the value of the createTag() attribute is true, the runtime must use this value as the tag name for including an instance of the component annotated with this annotation in a view. If this attribute is not specified on a usage of this annotation, the simple name of the class on which this annotation is declared, with the first character lowercased, is taken to be the value.
    
    Returns:
    
    the tag name.
    
    Default:
    
    ""
- - namespace
```
public abstract java.lang.String namespace
```
    If the value of the createTag() attribute is true, the value of this attribute is taken to be the tag library namespace into which this component is placed.
    
    Returns:
    
    the namespace.
    
    Default:
    
    "jakarta.faces.component"
