Declares that the
composite component whose contract is declared by the
<composite:interface> in which this element is nested
exposes an implementation of ValueHolder suitable for use
as the target of attached objects in the using page.
Any attached objects suitable for implementations of
ValueHolder may be attached to the composite component.
Consider this excerpt from the using page:
Line 2 refers to the
<composite:valueHolder> declaration on
line 2 of foo.xhtml:
It is possible to declare that a single
<composite:valueHolder> element should cause multiple
components within the <composite:implementation>
section to be the targets of an attached object in the
using page. Assuming the same using page excerpt as
above, the revised VDL view is:
In this case, the "targets" attribute on the
<composite:valueHolder> element, on line 2 above,
replaces the "name" attribute in the previous example. "targets" is a
list of ids of client ids (relative to the top level component)
within the <composite:implementation> section. In
this case, "targets" refers to the <h:inputText>
components on lines 6 and 7 above.
Please see <composite:interface> for a usage
example.

The value of this attribute maps back to the "for" attribute on an attachable object
nested within a composite component. If the "targets" attribute is not specified,
this value also represents the component ID of the target component within the
