The type of SIF_ExtendedQueryResults/SIF_Rows/R/C has been changed from ExtendedContentType to the new SelectedContentType. SelectedContentType is defined in similar fashion to ExtendedContentType but with xs:any/@processContents set to skip instead of lax. This type change prevents arbitrarily selected SIF elements from clashing with top-level common element definitions when differently defined elements share the same name.

Add item:

In addition to supporting query conditions that reference root object attributes, responding agents MUST now also support query conditions that reference any mandatory elements within the object, along with their mandatory attributes; see Respond to Requests for additional information.
