/**
|
50 |
|
|
* <p> "DocumentType" implementation (with no extensions for supporting
|
51 |
|
|
* any document typing information). This is a non-core DOM class,
|
52 |
|
|
* supporting the "XML" feature. </p>
|
53 |
|
|
*
|
54 |
|
|
* <p> <em>Few XML applications will actually care about this partial
|
55 |
|
|
* DTD support</em>, since it doesn't expose any (!) of the data typing
|
56 |
|
|
* facilities which can motivate applications to use DTDs. It does not
|
57 |
|
|
* expose element content models, or information about attribute typing
|
58 |
|
|
* rules. Plus the information it exposes isn't very useful; as one example,
|
59 |
|
|
* DOM exposes information about unparsed ENTITY objects, which is only used
|
60 |
|
|
* with certain element attributes, but does not expose the information about
|
61 |
|
|
* those attributes which is needed to apply that data! </p>
|
62 |
|
|
*
|
63 |
|
|
* <p> Also, note that there are no nonportable ways to associate even the
|
64 |
|
|
* notation and entity information exposed by DOM with a DocumentType. While
|
65 |
|
|
* there is a DOM L2 method to construct a DocumentType, it only gives access
|
66 |
|
|
* to the textual content of the <!DOCTYPE ...> declaration. </p>
|
67 |
|
|
*
|
68 |
|
|
* <p> In short, <em>you are strongly advised not to rely on this incomplete
|
69 |
|
|
* DTD functionality</em> in your application code.</p>
