      javax.faces.webapp.AttributeTag

All Implemented Interfaces:
IterationTag, Serializable

Deprecated! The - Faces implementation must now provide the implementation for this class.

Tag implementation that adds an attribute with a specified name and String value to the component whose tag it is nested inside, if the component does not already contain an attribute with the same name. This tag creates no output to the page currently being created.
