The use property
Invokes another object in the same document as a prototype for this object. The content of this property is
either a SOM expression (which cannot start with '#') or a '#' character followed by an XML ID.
Starting with XFA 2.4 the object used as a prototype no longer needs to be the child of
proto
. Any object
of the appropriate class can be used as a prototype.
If both
use
and
usehref
are non-empty
usehref
takes precedence.
The usehref property
Invokes an external object as a prototype for this object. The content of this property is an URL, followed
by '#', followed by either an XML ID or by som(SOM_expr) where
SOM_expr
represents a SOM expression.
The XML ID or SOM expression is resolved in the context of the external document.
If both
use
and
usehref
are non-empty
usehref
takes precedence.
