Java 5 Syntax Element - supported since JTransformer 2.3.

An attribute for annotationT facts.
Just to maintain the original syntax of annotations without arguments. Annotation is a marker annotation if the parenthesis's are omitted.
@marker instead of the normal annotation @marker().

id: annotationT
ID of the corresponding annotationT

@MyAnnotation
public void function(){
}

annotatedT(#Annotated, #Annotation),
annotationT(#Annotation, #Annotated, #Annotated, _, []),
markerAnnotationT(#Annotation),

ast_relation('Java',markerAnnotationT,[
     ast_arg(id,     mult(1,1,no ), id,   [annotationT])
]).
