/**

 *

 * Provides the classes for implementing

 * <a href="https://www.oasis-open.org/committees/download.php/14809/xml-catalogs.html">

 *     XML Catalogs OASIS Standard V1.1, 7 October 2005</a>.

 *

 * <p>

 * The Catalog API defines a standard solution for resolving external resources

 * referenced by XML documents. It is fully supported by the XML Processors

 * allowing application developers to configure a catalog through an XML processor

 * or system property or the jaxp.properties file to take advantage of the feature.

 * <p>

 * The XML Catalog API defines the following interfaces:

 * <ul>

 *     <li>{@link Catalog} -- The {@link Catalog} interface represents an entity

 *         catalog as defined by the Catalog standard. A {@link Catalog} object

 *         is immutable. Once created, it can be used to find matches in a

 *         {@code system}, {@code public} or {@code uri} entry.

 *         A custom resolver implementation may find it useful for locating local

 *         resources through a catalog.

 *     </li>

 *     <li>{@link CatalogFeatures} -- The {@link CatalogFeatures} class holds all

 *         of the features and properties the Catalog API supports, including

 *         {@code javax.xml.catalog.files}, {@code javax.xml.catalog.defer},

 *         {@code javax.xml.catalog.prefer}, and {@code javax.xml.catalog.resolve}.

 *     </li>

 *     <li>{@link CatalogManager} -- The {@link CatalogManager} class manages the

 *         creation of XML catalogs and catalog resolvers.

 *     </li>

 *     <li>{@link CatalogResolver} -- The {@link CatalogResolver} class is a

 *         {@code Catalog} resolver that implements {@link org.xml.sax.EntityResolver},

 *         {@link javax.xml.stream.XMLResolver}, {@link org.w3c.dom.ls.LSResourceResolver},

 *         and {@link javax.xml.transform.URIResolver}, and resolves external

 *         references using catalogs.

 *     </li>

 * </ul>

 * <p>

 * Unless otherwise noted, passing a null argument to

 * a constructor or method in any class or interface in this package will

 * cause a {@code NullPointerException} to be thrown.
