In the following sections, we'll cover ZK Bind's annotations used on a ZUL. They are all used in component's attribute and have general format described in Annotate in ZUML:

@AnnotationName(attr-value1, attr-name2=attr-value2)

@AnnotationName(attr-name1={attr-value1-1, attr-value1-2}, attr-name2=attr-value2)

Basically, the syntax consists of an annotation name with comma-separated key-value pairs. The binder treats an annotation's attribute value as an EL expression, and sets an EL expression without a attribute name to default attribute name "value". All annotations must define default attribute's value.

For each ZK Bind supported annotation, the way a binder evaluates an EL expression is slightly different. Some annotation's EL expressions are evaluated only once like @id and @init. some annotations have reserved attribute names, "before" and "after", like @load and @save.
