Hi Günther, First off, the documentation is incorrect in not listing the nillable attribute for the <value> element. It looks like there's some sort of glitch in the generated code when it comes to unmarshalling these values, though - you shouldn't get that parser error that you're seeing. >From a quick look at my test cases it looks like I didn't try out the case of a nillable <value> following another <value> (only as the first thing inside a <structure> or <collection>), and that's probably leaving the parser in the wrong state. I'll investigate this.
