+</Title>
+<Para>Elements may have attributes associated with them; since the Element
+interface inherits from Node, the generic Node interface method 
+<Function>getAttributes</Function> may be used to retrieve the set of all
+attributes for an element. </Para>
+<Para>There are methods on the Element interface to retrieve either an Attr
+object by name or an attribute value by name. In XML, where an attribute value
+may contain entity references, an Attr object should be retrieved to examine
+the possibly fairly complex sub-tree representing the attribute value. On the
+other hand, in HTML, where all attributes have simple string values, methods to
+directly access an attribute value can safely be used as a convenience. </Para>
+
+<Para>Before you can access an Attribute, you must first gain access to the
+associated Element.</Para> </Sect1>
+<Sect1> <Title><Anchor Id="SDK378"/>Setting the Attribute
+Values</Title>
+<Para>Attr objects inherit the Node interface, but since they are not actually
+child nodes of the element they describe, the DOM does not consider them part
+of the document tree. Thus, the Node attributes parentNode, previousSibling,
+and nextSibling have a null value for Attr objects. The DOM takes the view that
+attributes are properties of elements rather than having a separate identity
+from the elements they are associated with; this should make it more efficient
+to implement such features as default attributes associated with all elements
+of a given type. Furthermore, Attr nodes may not be immediate children of a
+DocumentFragment. However, they can be associated with Element nodes contained
+within a DocumentFragment. In short, users and implementors of the DOM need to
+be aware that Attr nodes have some things in common with other objects
+inheriting the Node interface, but they also are quite distinct. </Para> 
+<Para>The attribute's effective value is determined as follows:</Para> 
+<ItemizedList Mark="Bullet"> <ListItem> 
+<Para>If this attribute has been explicitly assigned any value, that value is
+the attribute's effective value</Para></ListItem> <ListItem> 
+<Para>Otherwise, if there is a declaration for this attribute, and that
+declaration includes a default value, then that default value is the
+attribute's effective value</Para></ListItem> <ListItem> 
+<Para>Otherwise, the attribute does not exist on this element in the structure
+model until it has been explicitly added.</Para></ListItem> </ItemizedList> 
+<Para>In XML, where the value of an attribute can contain entity references,
+the child nodes of the Attr node provide a representation in which entity
+references are not expanded. These child nodes may be either Text or
+EntityReference nodes. Because the attribute type may be unknown, there are no
+tokenized attribute values. </Para>

+<Sect1> <Title><Anchor Id="SDK279"/>Introduction to Attributes
+</Title>
+<Para>Elements may have attributes associated with them; since the Element
+interface inherits from Node, the generic Node interface method 
+<Function>getAttributes</Function> may be used to retrieve the set of all
+attributes for an element. </Para>
+<Para>There are methods on the Element interface to retrieve either an Attr
+object by name or an attribute value by name. In XML, where an attribute value
+may contain entity references, an Attr object should be retrieved to examine
+the possibly fairly complex sub-tree representing the attribute value. On the
+other hand, in HTML, where all attributes have simple string values, methods to
+directly access an attribute value can safely be used as a convenience. </Para>
+
+<Para>Before you can access an Attribute, you must first gain access to the
+associated Element.</Para> </Sect1>
+<Sect1> <Title><Anchor Id="SDK378"/>Setting the Attribute
+Values</Title>
+<Para>Attr objects inherit the Node interface, but since they are not actually
+child nodes of the element they describe, the DOM does not consider them part
+of the document tree. Thus, the Node attributes parentNode, previousSibling,
+and nextSibling have a null value for Attr objects. The DOM takes the view that
+attributes are properties of elements rather than having a separate identity
+from the elements they are associated with; this should make it more efficient
+to implement such features as default attributes associated with all elements
+of a given type. Furthermore, Attr nodes may not be immediate children of a
+DocumentFragment. However, they can be associated with Element nodes contained
+within a DocumentFragment. In short, users and implementors of the DOM need to
+be aware that Attr nodes have some things in common with other objects
+inheriting the Node interface, but they also are quite distinct. </Para> 
+<Para>The attribute's effective value is determined as follows:</Para> 
+<ItemizedList Mark="Bullet"> <ListItem> 
+<Para>If this attribute has been explicitly assigned any value, that value is
+the attribute's effective value</Para></ListItem> <ListItem> 
+<Para>Otherwise, if there is a declaration for this attribute, and that
+declaration includes a default value, then that default value is the
+attribute's effective value</Para></ListItem> <ListItem> 
+<Para>Otherwise, the attribute does not exist on this element in the structure
+model until it has been explicitly added.</Para></ListItem> </ItemizedList> 
+<Para>In XML, where the value of an attribute can contain entity references,
+the child nodes of the Attr node provide a representation in which entity
+references are not expanded. These child nodes may be either Text or
+EntityReference nodes. Because the attribute type may be unknown, there are no
+tokenized attribute values. </Para>
