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.

Associate an object to a key on this node. The object can later be

 This method returns a specialized object which implements the
specialized APIs of the specified feature and version. The
specialized object may also be obtained by using binding-specific
casting methods but is not necessarily expected to, as discussed in Mixed DOM implementations.

Params:
  • feature – The name of the feature requested (case-insensitive).
  • version –  This is the version number of the feature to test. If
  the version is null or the empty string, supporting
  any version of the feature will cause the method to return an
  object that supports at least one version of the feature.
Returns: Returns an object which implements the specialized APIs of
  the specified feature and version, if any, or null if
  there is no object which implements interfaces associated with that
  feature. If the DOMObject returned by this method
  implements the Node interface, it must delegate to the
  primary core Node and not return results inconsistent
  with the primary core Node such as attributes,
  childNodes, etc.

Tests whether two nodes are equal.

This method tests for equality of nodes, not sameness (i.e.,
whether the two nodes are references to the same object) which can be
tested with Node.isSameNode. All nodes that are the same
will also be equal, though the reverse may not be true.

Two nodes are equal if and only if the following conditions are
satisfied: The two nodes are of the same type.The following string
attributes are equal: nodeName, localName,
namespaceURI, prefix, nodeValue
, baseURI. This is: they are both null, or
they have the same length and are character for character identical.
The attributes NamedNodeMaps are equal.
This is: they are both null, or they have the same
length and for each node that exists in one map there is a node that
exists in the other map and is equal, although not necessarily at the
same index.The childNodes NodeLists are
equal. This is: they are both null, or they have the
same length and contain equal nodes at the same index. This is true
for Attr nodes as for any other type of node. Note that
normalization can affect equality; to avoid this, nodes should be
normalized before being compared.

For two DocumentType nodes to be equal, the following
conditions must also be satisfied: The following string attributes
are equal: publicId, systemId,
internalSubset.The entities
NamedNodeMaps are equal.The notations
NamedNodeMaps are equal.

On the other hand, the following do not affect equality: the
ownerDocument attribute, the specified
attribute for Attr nodes, the
isWhitespaceInElementContent attribute for
Text nodes, as well as any user data or event listeners
registered on the nodes.

Params:
  • arg – The node to compare equality with.
  • deep – If true, recursively compare the subtrees; if
  false, compare only the nodes themselves (and its
  attributes, if it is an Element).
Returns:If the nodes, and possibly subtrees are equal,
  true otherwise false.

When set, any possible children this node may have are removed and

the returned string does not contain any markup. No whitespace
normalization is performed, the returned string does not contain the
element content whitespaces . Similarly, on setting, no parsing is
performed either, the input string is taken as pure textual content.
