its value is changed to be the value
parameter. This
value is a simple string; it is not parsed as it is being set. So any
markup (such as syntax to be recognized as an entity reference) is
treated as literal text, and needs to be appropriately escaped by the
implementation when it is written out. In order to assign an
attribute value that contains entity references, the user must create
an Attr

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

of node simply returns a copy of this node.
