java.lang.Objectorg.apache.xml.dtm.ref.dom2dtm.DOM2DTMdefaultNamespaceDeclarationNode
This is a kluge to let us shove a declaration for xml: into the DOM2DTM model. Basically, it creates a proxy node in DOM space to carry the additional information. This is _NOT_ a full DOM implementation, and shouldn't be one since it sits alongside the DOM rather than becoming part of the DOM model. (This used to be an internal class within DOM2DTM. Moved out because I need to perform an instanceof operation on it to support a temporary workaround in DTMManagerDefault.) %REVIEW% What if the DOM2DTM was built around a DocumentFragment and there isn't a single root element? I think this fails that case... %REVIEW% An alternative solution would be to create the node _only_ in DTM space, but given how DOM2DTM is currently written I think this is simplest.

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 document and has a value of #IMPLIED in the DTD, then the

public void normalize()
Node
Text
nodes in the full depth of the sub-tree
underneath this Node
, including attribute nodes, into a
"normal" form where only structure (e.g., elements, comments,
processing instructions, CDATA sections, and entity references)
separates Text
nodes, i.e., there are neither adjacent
Text
nodes nor empty Text
nodes. This can
be used to ensure that the DOM view of a document is the same as if
it were saved and re-loaded, and is useful when operations (such as
XPointer lookups) that depend on a particular document tree
structure are to be used.In cases where the document contains
CDATASections
, the normalize operation alone may not be
sufficient, since XPointers do not differentiate between
Text
nodes and CDATASection
nodes.

public Document getOwnerDocument()
Node

or a DocumentType
which is not used with any Document

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 text it
contains unless it is a deep clone, 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 any other type
of node simply returns a copy of this node.
EntityReference

. In addition, clones of unspecified Attr
nodes are
specified. And, cloning Document
,
DocumentType
, Entity
, and
Notation
nodes is implementation dependent.
cloneNode
in interface Node
deep
- If true
, recursively clone the subtree under
the specified node; if false
, clone only the node
itself (and its attributes, if it is an Element
).
