Sam nailed it with his versioning idea. Getting PSP Certified is great, adding a few rss elements. What if the developer adds 10 or 15 of the new rss elements though? The PSP logo that gets displayed out there on the various websites should be pulled in via script. Prove to the PSP committee that your product support 2.03 or 2.06 etc and THAT PSP logo is the one that will display on the various websites with that version number actually showing on the svg image itself.
