      This is the XML Schema for the JSP Taglibrary
      descriptor.  All Taglibrary descriptors must
      indicate the tag library schema by using the Taglibrary
      namespace:

      https://jakarta.ee/xml/ns/jakartaee

      and by indicating the version of the schema by
      using the version element as shown below:

      xsi:schemaLocation="..."
      version="3.1">
      ...
      </taglib>

      The instance documents may indicate the published
      version of the schema using xsi:schemaLocation attribute
      for Jakarta EE namespace with the following location:

        This value is used by the JSP container to validate
        that a tag invocation has the correct body syntax and
        by page composition tools to assist the page author
        in providing a valid tag body.

        There are currently four values specified:

        tagdependent    The body of the tag is interpreted by the tag
                        implementation itself, and is most likely
                        in a different "language", e.g embedded SQL
                        statements.

        JSP             The body of the tag contains nested JSP
                        syntax.

        empty           The body must be empty

        scriptless      The body accepts only template text, EL

        The tld-extensionType is used to indicate
        extensions to a specific TLD element.

        It is used by elements to designate an extension block
        that is targeted to a specific extension designated by
        a set of extension elements that are declared by a
        namespace. The namespace identifies the extension to
        the tool that processes the extension.

        The type of the extension-element is abstract. Therefore,
        a concrete type must be specified by the TLD using
        xsi:type attribute for each extension-element.

        The extensibleType is an abstract base type that is used to
        define the type of extension-elements. Instance documents
        must substitute a known type to define the extension by
        using xsi:type attribute to define the actual type of
        extension-elements.
