All, This completed public comment at the end of April. There are two comments: 1. Credential element example has the wrong namespace. The example has the activity credential namespace... I'd suggest putting the credential element into the File Staging namespace. 2. Support X509 credentials but do not mandate a protocol that uses it. True. I'd propose adding some text to say that GridFTP could be used... but we do not see this as a widely deployed protocol in the HPCBP world to make part of the mandated set. Perhaps adding a URI for GridFTP so that people could use it... are the other file transfer protocols that could go in here as well? I'd propose that we incorporate this feedback and resubmit for publishing it ASAP. Steven
