 * <h3 id="JaxpProperties">jaxp.properties</h3>
 * {@code jaxp.properties} is a configuration file in standard
 * {@link java.util.Properties} format and typically located in the {@code conf}
 * directory of the Java installation. It contains the fully qualified
 * name of the implementation class with the key being the system property name
 * defined in <a href="#Factories">the table</a> above.
 * <p>
 * The {@code jaxp.properties} file is read only once by the implementation and
 * the values are then cached for future use.  If the file does not exist when
 * the first attempt is made to read from it, no further attempts
 * are made to check for its existence. It is not possible to change the value
 * of any property after it has been read for the first time.
 *
 * <h3 id="StAXProperties">stax.properties</h3>
 * {@code stax.properties} is a configuration file that functions the same as
 * {@code jaxp.properties} except that it is only used by StAX factory lookup.
 *
 * <h3 id="LookupProcedure">Lookup Procedure</h3>
 * The <a href="#Factories">JAXP Factories</a> follow the procedure described
 * below in order to locate and load the implementation class:
 *
 * <ul>
 * <li>
 * Use the system property as described in column System Property of the table
 * <a href="#Factories">JAXP Factories</a> above.
 * </li>
 * <li>
 * <p>
 * Use the configuration file <a href="#JaxpProperties">jaxp.properties</a> as
 * indicated in the table <a href="#Factories">JAXP Factories</a>. For StAX,
 * if <a href="#StAXProperties">stax.properties</a> exists, the factories will
 * first attempt to read from it instead of <a href="#JaxpProperties">jaxp.properties</a>.
 * </li>
 * <li>
 * <p>
 * Use the service-provider loading facility, defined by the
 * {@link java.util.ServiceLoader} class, to attempt to locate and load an
 * implementation of the service using the {@linkplain
 * java.util.ServiceLoader#load(java.lang.Class) default loading mechanism}:
 * the service-provider loading facility will use the {@linkplain
 * java.lang.Thread#getContextClassLoader() current thread's context class loader}
 * to attempt to load the service. If the context class
 * loader is null, the {@linkplain
 * ClassLoader#getSystemClassLoader() system class loader} will be used.
 *
 * <h3>{@link javax.xml.validation.SchemaFactory SchemaFactory}</h3>
 * In case of the {@link javax.xml.validation.SchemaFactory SchemaFactory},
 * each potential service provider is required to implement the method
 * {@link javax.xml.validation.SchemaFactory#isSchemaLanguageSupported(java.lang.String)
 * isSchemaLanguageSupported(String schemaLanguage)}.
 * The first service provider found that supports the specified schema language
 * is returned.
 *
 * <h3>{@link javax.xml.xpath.XPathFactory XPathFactory}</h3>
 * In case of the {@link javax.xml.xpath.XPathFactory XPathFactory},
 * each potential service provider is required to implement the method
 * {@link javax.xml.xpath.XPathFactory#isObjectModelSupported(String objectModel)
 * isObjectModelSupported(String objectModel)}.
 * The first service provider found that supports the specified object model is
 * returned.
 * </li>
 * <li>
 * <p>
 * Otherwise, the {@code system-default} implementation is returned, which is
 * equivalent to calling the {@code newDefaultInstance() or newDefaultFactory()}
 * method as shown in column System Default of the table
 * <a href="#Factories">JAXP Factories</a> above.
 *
 * <h3>{@link javax.xml.validation.SchemaFactory SchemaFactory}</h3>
 * In case of the {@link javax.xml.validation.SchemaFactory SchemaFactory},
 * there must be a {@linkplain javax.xml.validation.SchemaFactory#newDefaultInstance()
 * platform default} {@code SchemaFactory} for W3C XML Schema.
 *
 * <h3>{@link javax.xml.xpath.XPathFactory XPathFactory}</h3>
 * In case of the {@link javax.xml.xpath.XPathFactory XPathFactory},
 * there must be a
 * {@linkplain javax.xml.xpath.XPathFactory#newDefaultInstance() platform default}
 * {@code XPathFactory} for the W3C DOM, i.e.
 * {@link javax.xml.xpath.XPathFactory#DEFAULT_OBJECT_MODEL_URI DEFAULT_OBJECT_MODEL_URI}.

 * <h2>Implementation Specific Features and Properties</h2>
 *
 * In addition to the standard features and properties described within the public
 * APIs of this module, the JDK implementation supports a further number of
 * implementation specific features and properties. This section describes the
 * naming convention, System Properties, jaxp.properties, scope and order,
 * and processors to which a property applies. A table listing the implementation
 * specific features and properties which the implementation currently supports
 * can be found at the end of this note.
 *
 * <h3 id="NamingConvention">Naming Convention</h3>
 * The names of the features and properties are fully qualified, composed of a
 * prefix and name.
 *
 * <h4>Prefix</h4>
 * The prefix for JDK features and properties, as well as their corresponding
 * System Properties if any, is defined as:
 * <pre>
 *     {@code jdk.xml.}
 * </pre>
 *
 * <h4>Name</h4>
 * A name may consist of one or multiple words that are case-sensitive.
 * All letters of the first word are in lowercase, while the first letter of
 * each subsequent word is capitalized.
 * <p>
 * An example of a property that indicates whether an XML document is standalone
 * would thus have a format:
 * <pre>
 *     {@code jdk.xml.isStandalone}
 * </pre>
 * and a corresponding System Property:
 * <pre>
 *     {@systemProperty jdk.xml.isStandalone}
 * </pre>
 *
 * <h3>System Properties</h3>
 * A property may have a corresponding System Property with the same name.
 * A System Property should be set prior to the creation of a processor and
 * may be cleared afterwards.
 *
 * <h3>jaxp.properties</h3>
 * A system property can be specified in the <a href="#JaxpProperties">jaxp.properties</a>
 * file to set the behavior for all invocations of the JDK. The format is
 * {@code system-property-name=value}. For example:
 * <pre>
 *     {@code jdk.xml.isStandalone=true}
 * </pre>
 *
 * <h3 id="ScopeAndOrder">Scope and Order</h3>
 * The {@link javax.xml.XMLConstants#FEATURE_SECURE_PROCESSING} feature
 * (hereafter referred to as secure processing) is required for XML processors
 * including DOM, SAX, Schema Validation, XSLT, and XPath. When secure processing
 * is set to true, security related features and properties, such as those flagged
 * as {@code "security: yes"} (hereafter referred to as security properties) in
 * table <a href="#Features">Implementation Specific Features</a> and
 * <a href="#Properties">Properties</a>,
 * are enforced. Such enforcement includes setting security properties and features
 * to more restrictive values and limits as shown in {@code "Value"}'s
 * subcolumn {@code "Enforced"} in the tables. When secure processing
 * is set to false, however, the property values will not be affected.
 * <p>
 * When the Java Security Manager is present, secure processing is set to true
 * and can not be turned off. The security properties are therefore enforced.
 * <p>
 * Properties specified in the jaxp.properties file affect all invocations of
 * the JDK, and will override their default values, or those that may have been
 * set by secure processing.
 * <p>
 * System properties, when set, affect the invocation of the JDK and override
 * the default settings or those that may have been set in jaxp.properties or
 * by secure processing.
 * <p>
 * JAXP properties specified through JAXP factories or processors (e.g. SAXParser)
 * take preference over system properties, the jaxp.properties file, as well as
 * secure processing.
 *
 * <h3 id="Processor">Processor Support</h3>
 * Features and properties may be supported by one or more processors. The
 * following table lists the processors by IDs that can be used for reference.
