JSF attributeTag
This tag is used to add attribute to the nearest parent component. This is name/value pair where name takes the attribute name which will be set to the component and value takes the value of the attribute. In this example, command button tag is assigned only one attribute "id", then attribute tag is used to assign more attributes and its values. For example, instead of specifying "value" attribute and its value "Click" ( i.e. value="Click") in commandButton tag parallel to "id" attribute, this has been associated to the component using attribute tag.
