package org.apache.xerces.dom;
62
* Entity nodes hold the reference data for an XML Entity -- either
63
* parsed or unparsed. The nodeName (inherited from Node) will contain
64
* the name (if any) of the Entity. Its data will be contained in the
65
* Entity's children, in exactly the structure which an
66
* EntityReference to this name will present within the document's
69
* Note that this object models the actual entity, _not_ the entity
70
* declaration or the entity reference.
72
* An XML processor may choose to completely expand entities before
73
* the structure model is passed to the DOM; in this case, there will
74
* be no EntityReferences in the DOM tree.
76
* Quoting the 10/01 DOM Proposal,
78
* "The DOM Level 1 does not support editing Entity nodes; if a user
79
* wants to make changes to the contents of an Entity, every related
80
* EntityReference node has to be replaced in the structure model by
81
* a clone of the Entity's contents, and then the desired changes
82
* must be made to each of those clones instead. All the
83
* descendants of an Entity node are readonly."
85
* I'm interpreting this as: It is the parser's responsibilty to call
86
* the non-DOM operation setReadOnly(true,true) after it constructs
87
* the Entity. Since the DOM explicitly decided not to deal with this,
88
* _any_ answer will involve a non-DOM operation, and this is the
92
