/**
* Defines an abstract implementation of a factory for
* getting XMLEventWriters and XMLStreamWriters.
*
* The following table defines the standard properties of this specification.
* Each property varies in the level of support required by each implementation.
* The level of support required is described in the 'Required' column.
*
* <table border="2" rules="all" cellpadding="4">
* <thead>
* <tr>
* <th align="center" colspan="2">
* Configuration parameters
* </th>
* </tr>
* </thead>
* <tbody>
* <tr>
* <th>Property Name</th>
* <th>Behavior</th>
* <th>Return type</th>
* <th>Default Value</th>
* <th>Required</th>
* </tr>
* <tr><td>javax.xml.stream.isRepairingNamespaces</td><td>defaults prefixes on the output side</td><td>Boolean</td><td>False</td><td>Yes</td></tr>
* </tbody>
* </table>
*
* <p>The following paragraphs describe the namespace and prefix repair algorithm:</p>
*
* <p>The property can be set with the following code line:
* <code>setProperty("javax.xml.stream.isRepairingNamespaces",new Boolean(true|false));</code></p>
*
* <p>This property specifies that the writer default namespace prefix declarations.
* The default value is false. </p>
*
* <p>If a writer isRepairingNamespaces it will create a namespace declaration
* on the current StartElement for
* any attribute that does not
* currently have a namespace declaration in scope. If the StartElement
* has a uri but no prefix specified a prefix will be assigned, if the prefix
* has not been declared in a parent of the current StartElement it will be declared
* on the current StartElement. If the defaultNamespace is bound and in scope
* and the default namespace matches the URI of the attribute or StartElement
* QName no prefix will be assigned.</p>
*
* <p>If an element or attribute name has a prefix, but is not
* bound to any namespace URI, then the prefix will be removed
* during serialization.</p>
*
* empty-element tag are bound to different namespace URIs and
* are using the same prefix then the element or the first
* occurring attribute retains the original prefix and the
* following attributes have their prefixes replaced with a
* new prefix that is bound to the namespace URIs of those
* attributes. </p>
*
* <p>If an element or attribute name uses a prefix that is
* bound to a different URI than that inherited from the
* namespace context of the parent of that element and there
* is no namespace declaration in the context of the current
* element then such a namespace declaration is added. </p>
*
* <p>If an element or attribute name is bound to a prefix and
* there is a namespace declaration that binds that prefix
* to a different URI then that namespace declaration is
* either removed if the correct mapping is inherited from
* the parent context of that element, or changed to the
* namespace URI of the element or attribute using that prefix.</p>

* available to the runtime.
