How do you use the SPSiteDataQuery to find SPListItems in Document Libraries where the Name starts with 'foo'?
<Where><BeginsWith><FieldRef Name='Name'/><Value Type='Text'>Foo</Value></BeginsWith></Where>
Doesn't return a thing. I can change 'Name' to 'Title' and get something. So what is the right SharePoint FieldReference (CAML) that matches to SPListItem Name?
