|
|
* This is a non-core DOM class, supporting the "XML" feature. </p>
|
| 46 |
|
|
*
|
| 47 |
|
|
* <p> Unlike other DOM APIs in the "XML" feature, this one fully
|
| 48 |
|
|
* exposes the functionality it describes. So there is no reason
|
| 49 |
|
|
* inherent in DOM to avoid using this API, unless you want to rely
|
| 50 |
|
|
* on NOTATION declarations to associate meaning with your PIs;
|
| 51 |
|
|
* there is no vendor-neutal way to record those notations in DOM.</p>
|
| 52 |
|
|
*
|
| 53 |
|
|
* <p> Also of note is that PI support is part of SAX, so that XML
|
| 54 |
|
|
* systems using PIs can choose among multiple APIs. </p>
