public final class AttrImpl extends NodeImpl implements Attr
Some of the fields may have package visibility, so other classes belonging to the DOM implementation can easily access them while maintaining the DOM tree structure.

default values from other schemas similarly but applications should
use Document.normalizeDocument() to guarantee this
information is up-to-date.getSpecified in interface Attrpublic String getValue()

AttrownerElement of this attribute
can be retrieved using the method Document.getElementById
. The implementation could use several ways to determine if an
attribute node is known to contain an identifier:
Document.normalizeDocument(), the post-schema-validation
infoset contributions (PSVI contributions) values are used to
determine if this attribute is a schema-determined ID attribute using
the
schema-determined ID definition in [XPointer]
.
Document.normalizeDocument(), the infoset [type definition] value is used to determine if this attribute is a DTD-determined ID
attribute using the
DTD-determined ID definition in [XPointer]
.
Element.setIdAttribute(),
Element.setIdAttributeNS(), or
Element.setIdAttributeNode(), i.e. it is an
user-determined ID attribute;
Note: XPointer framework (see section 3.2 in [XPointer] ) consider the DOM user-determined ID attribute as being part of the XPointer externally-determined ID definition.
Document.normalizeDocument(), all user-determined ID
attributes are reset and all attribute nodes ID information are then
reevaluated in accordance to the schema used. As a consequence, if
the Attr.schemaTypeInfo attribute contains an ID type,
isId will always return true.
