+        The position can be in the same or in an another document. It can also
+        be within the range!
+
+        \warning The range has to include at least two nodes or has to be a
+        SwDoc::IsColumnSelection, because the rPam is treated [mark, point[.
+
+        Normally this function should work only with content nodes. But there
+        is a special case used by SwDoc::Paste, which starts the SwPaM at the
+        content start node. This position doesn't contain any content:
+
+        @code
+        SwNodeIndex aSourceIdx( rSource.GetNodes().GetEndOfExtras(), 1 );
+        @endcode
+
+        This is important, because it prevents merging of the first node of
+        the range into the node pointed to by \p rPos.
+        As a result this keeps all properties of the first real content node,
+        which is the 2nd, including the Flys and the page description. In this
+        case the first (fake) node is silently dropped and all other nodes are
+        just copied.

+        that the caller took care of verifying this constraint already.
