The previous set of examples I posted were from later Pali literature
(Mahaava.msa) so I've been looking out for cases of saka and attano
in canonical literature as well. Here are two examples. The first
uses saka in a compound, the second as a free-standing adjective. I
don't have the exact references handy, but they are both from the
early episodes of the Mahaavagga. Mucalinda and Yasa are both devoted
their own sections, iirc, so they should be easy to find.
