value if upon examining the image data it determines that the image data is of a different type. Which
image types are supported is implementation-defined.
The href property
Specifies a reference to an external entity.
The set of supported URI schemes (e.g.,
http:
,
ftp:
) is implementation-defined.
The id property
A unique identifier that may be used to identify this element as a target.
The maxLength property
Specifies the maximum (inclusive) allowable length of the content, or
-1
to signify that there is no
maximum length imposed on the content. The default is
-1
.
The interpretation of this property is affected by the content type. This specification only defines the
interpretation of this property for content types that represent some form of textual content. In this case
this property specifies the maximum (inclusive) allowable length of the content in characters. For instance,
where the content type is
text/plain
this property represents the maximum (inclusive) number of
characters of plain text content. In kind, where the content type is "text/html" this property represents the
maximum (inclusive) number of characters of content excluding markup, insignificant whitespace, etc.
The name property
An identifier that may be used to identify this element in script expressions.
The transferEncoding property
The encoding of binary content in the referenced document.
none
The referenced document is not encoded. If the referenced document is specified via a URI then it
will be transferred as a byte stream. If the referenced document is inline it must conform to the
restrictions on PCDATA.
base64
The binary content is encoded in accordance with the base64 transfer encoding s specified in
[RFC2045].
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.
