This tag associates an attribute with the nearest parent UIComponent.
When the value is not an EL expression, this tag has the same effect as calling
Component.Set_Attribute (Name, Value). When the attribute name specified
matches a standard property of the component, that property is set.
However it is also valid to assign attributes to components using any
arbitrary name; the component itself won't make any use of these but
other objects such as custom renderers, validators or action listeners
can later retrieve the attribute from the component by name.
When the value is an EL expression, this tag has the same effect as
calling Component.Set_Attribute (Tag, Value). A call to method
Component.Get_Attribute (Name) will then cause that expression to
be evaluated and the result of the expression is returned,
not the original EL expression string.
See the ASF.Components.Base package for more details.
Unless otherwise specified, all attributes accept static values or EL expressions.
Sets the specified name and attribute on the parent UIComponent.
If the "value" specified is not a literal, it will instead set the ValueExpression
on the UIComponent.
