The signatureProperties element
An element holding properties of an XML digital signature. This element is reserved for future use.
<signatureProperties
Properties:
id="xml-id"
use="cdata"
usehref="cdata"
>
</signatureProperties>
The signatureProperties element is used within the following other elements:
proto signData
This element is reserved for future versions of XFA.
The id property
A unique identifier that may be used to identify this element as a target.
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.
