Note that this models the entity itself not the entity * declaration. DOMEntity declaration modeling has been left for a * later Level of the DOM specification. *

The nodeName attribute that is inherited from * DOMNode contains the name of the entity. *

An XML processor may choose to completely expand entities before the * structure model is passed to the DOM; in this case there will be no * DOMEntityReference nodes in the document tree. *

XML does not mandate that a non-validating XML processor read and * process entity declarations made in the external subset or declared in * external parameter entities. This means that parsed entities declared in * the external subset need not be expanded by some classes of applications, * and that the replacement value of the entity may not be available. When * the replacement value is available, the corresponding DOMEntity * node's child list represents the structure of that replacement text. * Otherwise, the child list is empty. *

The DOM Level 2 does not support editing DOMEntity nodes; if a * user wants to make changes to the contents of an DOMEntity, * every related DOMEntityReference node has to be replaced in the * structure model by a clone of the DOMEntity's contents, and * then the desired changes must be made to each of those clones instead. * DOMEntity nodes and all their descendants are readonly. *

An DOMEntity node does not have any parent.If the entity * contains an unbound namespace prefix, the namespaceURI of * the corresponding node in the DOMEntity node subtree is * null. The same is true for DOMEntityReference * nodes that refer to this entity, when they are created using the * createEntityReference method of the DOMDocument * interface. The DOM Level 2 does not support any mechanism to resolve * namespace prefixes. *
