* Uses a pluggable InvCatalogConvertIF to transform the JDOM tree to the thredds.catalog objects.
* The converters are registered based on the namespace used. We are supporting: <ul>
* <li> the older "0.6" spec, namespace "http://www.unidata.ucar.edu/thredds"
* <li> the current 1.0/1.1 spec, namespace "http://www.unidata.ucar.edu/namespaces/thredds/InvCatalog/v1.0"
* </ul>
* The schemas are read from a local resource, see XMLEntityResolver

/*
* <h3>Default catalog parsing</h3>
*
* InvCatalogFactory allows parsers that handle different catalog versions to be registered
* by the application. These factories may also use different XML parsers. Usually you call
* InvCatalogFactory.getDefaultFactory(), which already has the default factories for catalog
* versions. The default factories validate the catalog XML, and require jdom.jar and a validating
* parser like the one that ships with jdk1.4.
*
* <h3>Nonvalidating catalog parsing</h3>
* To use a nonvalidating, small parser that does not need jdom.jar or any external parser do the
* following before you make any other InvCatalogFactory calls:
* <pre>
InvCatalogFactory myFactory = new InvCatalogFactory();
myFactory.registerCatalogFactory("0.6", new thredds.catalog.parser.nano.Catalog6());
InvCatalogFactory.setDefaultFactory( myFactory);
* </pre>
*
* <h3>Custom catalog parsing</h3>
* You may also instantiate an InvCatalogFactory and register your
* own factories, for example:
* <pre>
InvCatalogFactory myFactory = new InvCatalogFactory();
myFactory.registerCatalogFactory("0.6", new MyInvCatalogFactory());
InvCatalogFactory.setDefaultFactory( myFactory);
</pre>
*
* <h3>Custom metadata parsing</h3>
* InvCatalogFactory also allows you to register parsers for specialized metadata elements that
* appear in the catalog.xml. These parsers are called "metadata factories" and must implement
* the InvMetadataFactoryIF interface.
* Example:
* <pre>
InvCatalogFactory catFactory = InvCatalogFactory.getDefaultFactory();
catFactory.registerMetadataFactory(MetadataType.WMS, new myWMSFactory());
</pre>
* In this example, any metadata element of type MetadataType.WMS will be passed
* to your factory when the catalog is parsed. myWMSFactory will turn it into an
* Object, which will be available through the InvMetadata.getContentObject() call.
*/
