    Absolutely - I would love to. Quoting directly from the TC Process on
    the OASIS site (http://www.oasis-open.org/committees/process.php):
    
    "The purpose of the TC's public comment facility is to receive comments
    from the public and is not for public discussion. Comments will be
    publicly archived, and will be forwarded to one or more TC members
    including the TC chair. TCs shall not be required to respond to
    comments."
    
    In a nutshell, this means the TC has a formal process and method to take
    comments from non-members, such as those circulating on this list. You
    can either submit a comment by sending it to
    emergency-comment@lists.oasis-open.org, or you can click the "Send A
    Comment" button on the EM TC page located at the following URL:
    
    http://www.oasis-open.org/committees/tc_home.php?wg_abbrev=emergency
    
    Those who have participated in the demo in DC have some incredibly
    valuable lesson's learned from your experience, and sending this
    information back into the TC is a way for us, as a group, to address
    those comments and improve the standard before its final approval.
    
    We look forward to hearing your comments - Allen
