Well, AFAICT, the script only applies to SPs that support SAML V2.0 (not SAML V1.1). That's okay. I think that's the sweet spot for this application. I would suggest that you focus on SAML V2.0 SPs before expanding to other protocols and entities.

The InCommon Federation is interested in using SAMLmetaJS. Currently we have a forms-based UI in production but we have an alternate interface under development. We call the latter "XML Submission" and it's a dead ringer use case for this tool. Initially, we are targeting SAML V2.0-only SPs, so the current functionality of SAMLmetaJS is a good fit for us. Please keep up the good work!

Thanks, Tom. The priority on this project depends on if somebody finds it useful. So if InCommon and PEER is finding the software useful, I'll gear up the development, and make it more stable.
