Nested elements. A tandem orientation P{wd19.3} derivative is inserted into the w coding region of the original wd1 element. One of the two is deleted for 2.0kb from the 3' end.
construct_comment: Consists of nested element P{X88b} inserted in same orientation at 3\' end of original P{wdl9.3} element; nested element and composite element P{wd19.3+X88} share a common P3\' end.
