Connection Set Element Reference

The uri element
This element declares the location of the sample document or schema for its parent.
<uri
Properties:
id="xml-id"
name="xml-id"
use="cdata"
usehref="cdata"
>
...pcdata...
</uri>
The uri element is used within the following other elements:
xmlConnection xsdConnection
For security reasons this URI should not be honoured if it points outside the enclosing XDP or PDF
package, unless the entire package is trusted.
Content
The URI for the sample document or schema.
The id property
An identifier which may be used to identify this element in URIs.
The name property
An identifier that may be used to identify this element in script expressions.
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.
