/**
 * Class {@code ReferenceUriSchemesSupported} is a printing attribute class an
 * enumeration, that indicates a "URI scheme," such as "http:" or "ftp:", that a
 * printer can use to retrieve print data stored at a {@code URI} location. If a
 * printer supports doc flavors with a print data representation class of
 * {@code "java.net.URL"}, the printer uses instances of class
 * {@code ReferenceUriSchemesSupported} to advertise the {@code URI} schemes it
 * can accept. The acceptable {@code URI} schemes are included as service
 * attributes in the lookup service; this lets clients search the for printers
 * that can get print data using a certain {@code URI} scheme. The acceptable
 * {@code URI} schemes can also be queried using the capability methods in
 * interface {@code PrintService}. However, {@code ReferenceUriSchemesSupported}
 * attributes are used solely for determining acceptable {@code URI} schemes,
 * they are never included in a doc's, print request's, print job's, or print
 * service's attribute set.
 * <p>
 * The Internet Assigned Numbers Authority maintains the
 * <a href="http://www.iana.org/assignments/uri-schemes.html">official list of
 * URI schemes</a>.
 * <p>
 * Class {@code ReferenceUriSchemesSupported} defines enumeration values for
 * widely used {@code URI} schemes. A printer that supports additional
 * {@code URI} schemes can define them in a subclass of class
 * {@code ReferenceUriSchemesSupported}.
 * <p>
 * <b>IPP Compatibility:</b> The category name returned by {@code getName()} is
 * the IPP attribute name. The enumeration's integer value is the IPP enum
 * value. The {@code toString()} method returns the IPP string representation of
 * the attribute value.
