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

        http://java.sun.com/xml/ns/j2ee

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

            <taglib xmlns="http://java.sun.com/xml/ns/j2ee"
              xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

              version="2.0">
              ...
            </taglib>

        The instance documents may indicate the published
        version of the schema using xsi:schemaLocation attribute
        for J2EE namespace with the following location:

        http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd

        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
