Why does the root element of a DFDL schema need to specify any properties?

[Costello, Roger L.]

Hi Folks,

Consider a root element that has a complexType. The root element we declare in 
the DFDL schema is just an artifact of XML Schema. There is no "root element" 
in the data format. The purpose of the DFDL schema is to specify the properties 
of a data format. Since the data format has no "root element," there should be 
no properties to specify in the DFDL schema root element. Yes?
