    <description>
        The display tag library is an open source suite of custom tags that provide high level web presentation patterns
        which will work in a MVC model, and provide a significant amount of functionality while still being simple and
        straight-forward to use. The primary tag in the library is the Table tag.

        <description>
            Displays a list in an html table, formatting each item in the list according to the Column tags nested
            inside of this tag. Use the list attribute to indicate the Collection of data, in some scope, that the tag
            should operate on. Supports the export of the list data to alternative formats such as CSV, Excel, and XML.
            The contents of the list can be sorted, and the list can be broken into individual pages for display. If you
            use this tag in Struts, or in some other framework where the page is included via a jsp:include, you should
            use the requestURI attribute to indicate where tag generated links should point.

                reference to the object used as source for the table. Can be an expression like
                requestScope.object.property. In the EL version of the taglibrary this must be an EL expression which
                points to the source object.

                uid_rowNum to refer to the current row number. Two tables in the same page can't have the same id
                (paging and sorting will affect both). If no "htmlId" is specified the same value will be used for the
                html id of the generated table.

            or if the 'property' attribute is null, then the results of evaluating the JSP body of the tag.

            <description>
                name of the property in the bean specified in the parent table tag (via the "name" attribute) which will
                be used to sort values in the column. This can be used when the column body is filled or a decorator is
                used and column should sort on undeorated values.

            <description>
                Resource key used to lookup the title value. Only works if "title" is not defined. Works together with a
                configured I18nResourceProvider, specified via the displaytag.properties file. By default, if JSTL is
                available, the JSTL provider is used, which makes this attribute work the same as fmt:message's key
                property.

            <description>
                By default, null values don't appear in the list. By setting 'nulls' to 'true', then null values will
                appear as "null" in the list (mostly useful for debugging). Defaults to 'false'.
