Creates a DOM Document object of the specified type with its document
element.
param
namespaceURI The namespace URI of the document element to
create.
param
qualifiedName The qualified name of the document element to be
created.
param
doctype The type of document to be created or null.
When doctype is not null, its
Node.ownerDocument attribute is set to the document
being created.
return
A new Document object.
exception
DOMException
INVALID_CHARACTER_ERR: Raised if the specified qualified name
contains an illegal character.
NAMESPACE_ERR: Raised if the qualifiedName is
malformed, if the qualifiedName has a prefix and the
namespaceURI is null, or if the
qualifiedName has a prefix that is "xml" and the
namespaceURI is different from "
http://www.w3.org/XML/1998/namespace" , or if the DOM
implementation does not support the "XML" feature but
a non-null namespace URI was provided, since namespaces were
defined by XML.
WRONG_DOCUMENT_ERR: Raised if doctype has already
been used with a different document or was created from a different
implementation.
NOT_SUPPORTED_ERR: May be raised by DOM implementations which do
not support the "XML" feature, if they choose not to support this
method. Other features introduced in the future, by the DOM WG or
in extensions defined by other groups, may also demand support for
this method; please consult the definition of the feature to see if
it requires this method.

throw new DOMException(DOMException.NOT_SUPPORTED_ERR, "Not Implemented");
Creates an empty DocumentType node. Entity declarations
and notations are not made available. Entity reference expansions and
default attribute additions do not occur. It is expected that a
future version of the DOM will provide a way for populating a
DocumentType.
param
qualifiedName The qualified name of the document type to be
created.
param
publicId The external subset public identifier.
param
systemId The external subset system identifier.
return
A new DocumentType node with
Node.ownerDocument set to null.

Test if the DOM implementation implements a specific feature.
param
feature The name of the feature to test (case-insensitive). The
values used by DOM features are defined throughout the DOM Level 2
specifications and listed in the section. The name must be an XML
name. To avoid possible conflicts, as a convention, names referring
to features defined outside the DOM specification should be made
unique.
param
version This is the version number of the feature to test. In
Level 2, the string can be either "2.0" or "1.0". If the version is
not specified, supporting any version of the feature causes the
method to return true.
return
true if the feature is implemented in the
specified version, false otherwise.
if (feature.equals("Core")) {
return version == null || version.equals("1.0") || version.equals("2.0");
}
return false;
