/**
 * Defines the Java API for XML Processing (JAXP), the Streaming API for XML (StAX),
 * the Simple API for XML (SAX), and the W3C Document Object Model (DOM) API.
 *
 * @implNote
 * <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>Naming Convention</h3>
 * The names of the features and properties are fully qualified, composed of a
 * prefix and name.
 * <p>
 * <h4>Prefix</h4>
 * The prefix for JDK properties is defined as:
 * <pre>
 *     {@code http://www.oracle.com/xml/jaxp/properties/}
 * </pre>
 *
 * The prefix for features:
 * <pre>
 *     {@code http://www.oracle.com/xml/jaxp/features/}
 * </pre>
 *
 * The prefix for System Properties:
 * <pre>
 *     {@code jdk.xml.}
 * </pre>
 * <p>
 * <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 http://www.oracle.com/xml/jaxp/properties/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 that has the same name
 * except for the prefix as shown above. 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 {@code jaxp.properties} 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>
 * <p>
 * For details about the JAXP configuration file {@code jaxp.properties}, refer to
 * {@link javax.xml.parsers.SAXParserFactory#newInstance() SAXParserFactory#newInstance}.
 *
 * <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. Any properties flagged
 * as {@code "security: yes"} (hereafter referred to as security properties) in
 * table <a href="#FeaturesAndProperties">Features And Properties</a>
 * are enforced when secure processing is set to true. Such enforcement includes
 * setting security features to true and limits to the defined values shown in
 * the table. The property values will not be affected, however, when setting
 * secure processing to false.
 * <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.
 * <p>
 *
 * <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.
 * <p>
 *
 * <table class="plain" id="Processors">
