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).

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

Element copies all attributes and their
values, including those generated by the XML processor to represent
defaulted attributes, but this method does not copy any children it
contains unless it is a deep clone. This includes text contained in
an the Element since the text is contained in a child
Text node. Cloning an Attribute directly,
as opposed to be cloned as part of an Element cloning
operation, returns a specified attribute (specified is
true). Cloning an Attribute always clones
its children, since they represent its value, no matter whether this
is a deep clone or not. Cloning an EntityReference
automatically constructs its subtree if a corresponding
Entity is available, no matter whether this is a deep
clone or not. Cloning any other type of node simply returns a copy of
this node.

specified. And, cloning Document,

org.w3c.dom.NodeNode's specialized interface
(see ).What are the relations between Node.isSupported and
Node3.getInterface?Should we rename this method (and also
DOMImplementation.getInterface?)?getInterface can return a node that
doesn't actually support the requested interface and will lead to a
cast exception. Other solutions are returning null or throwing an
exception.getInterface in interface org.w3c.dom.Nodeorg.w3c.dom.Nodefeature - The name of the feature requested (case-insensitive).Node which implements the
specialized APIs of the specified feature, if any, or
null if there is no alternate Node which
implements interfaces associated with that feature. Any alternate
Node returned by this method must delegate to the
primary core Node and not return results inconsistent
with the primary core Node such as key,
attributes, childNodes, etc.
