dataset output in "diffgram" format- I don't want this.

I am debugging an application where the .getxml method on a dataset is being
returned in "diffgram" format instead of "just the records" as I am
expecting. The dataset is composed of 8 tables and I iterated through the
tables and called AcceptChanges on each of the tables, but when I call
..getxml on the dataset after this operation- I continue to retrieve the
dataset in diffgram format. Then I created another dataset and "loaded" this
diffgram data using a textreader- and output this dataset and it STILL
produces XML in diffgram format.

I'm stumped. Any help is appreciated.

A fragment of a typical element appears below:

<WorkingHours diffgr:id="WorkingHours35" msdata:rowOrder="34"
diffgr:hasChanges="inserted">
<VendorID>21271</VendorID>
<FacilityID>1</FacilityID>
