<DL>
<DD>Takes relational values referenced by an Instance and copies them from a
 source dataset to a destination dataset. The instance references are
 updated to be valid for the destination dataset. The instance may have the 
 structure (i.e. number and attribute position) of either dataset (this
 affects where references are obtained from). Only works if the number
 of relational attributes is the same in both indices (implicitly these 
 relational attributes should be semantically same but just with shifted 
 positions).
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>instance</CODE> - the instance containing references to relations 
                                in the source dataset that will have references 
                                updated to be valid for the destination dataset.<DD><CODE>instSrcCompat</CODE> - true if the instance structure is the same as 
                                the source, or false if it is the same as the 
                                destination (i.e. which of the relational 
                                attribute indices contains the correct 
                                locations for this instance).<DD><CODE>srcDataset</CODE> - the dataset for which the current instance 
                                relationvalue references are valid (after any 
                                position mapping if needed)<DD><CODE>srcLoc</CODE> - an AttributeLocator containing the indices of
