Attr.specified Property

If this attribute was explicitly given a value in the original document, this is

true
; otherwise, it is
false
. Note that the implementation is in charge of this attribute, not the user. If the user changes the value of the attribute (even if it ends up having the same value as the default value) then the
specified
flag is automatically flipped to
true
. To re-specify the attribute as the default value from the DTD, the user must delete the attribute. The implementation will then make a new attribute available with
specified
set to
false
and the default value (if one exists).
In summary: If the attribute has an assigned value in the document then
specified
is
true
, and the value is the assigned value. If the attribute has no assigned value in the document and has a default value in the DTD, then
specified
is
false
, and the value is the default value in the DTD. If the attribute has no assigned value in the document and has a value of #IMPLIED in the DTD, then the attribute does not appear in the structure model of the document. If the
ownerElement
attribute is
null
(i.e. because it was just created or was set to
null
by the various removal and cloning operations)
specified
is
true
.
