DynamicAttributes (JSP 4.0 API Documentation - Apache Tomcat 11.0.25)
Description: declaration: package: jakarta.servlet.jsp.tagext, interface: DynamicAttributes

# Interface DynamicAttributes

public interface DynamicAttributes
For a tag to declare that it accepts dynamic attributes, it must implement this interface. The entry for the tag in the Tag Library Descriptor must also be configured to indicate dynamic attributes are accepted.
For any attribute that is not declared in the Tag Library Descriptor for this tag, instead of getting an error at translation time, the `setDynamicAttribute()` method is called, with the name and value of the attribute. It is the responsibility of the tag to remember the names and values of the dynamic attributes.

Since:
  JSP 2.0
