# Subject: LAST CALL: XEP-$xepnum ($title)
# Body:
#    This message constitutes notice of a Last Call
#    for comments on XEP-$xepnum ($title).
#
#    Abstract: $abstract
#
#    URL: https://xmpp.org/extensions/xep-$xepnum.html
#
#    This Last Call begins today and shall end at the close

#
#    Please consider the following questions during this Last Call and
#    send your feedback to the standards@xmpp.org discussion list:
#
#    1. Is this specification needed to fill gaps in the XMPP
#       protocol stack or to clarify an existing protocol?
#    2. Does the specification solve the problem stated in the
#       introduction and requirements?
#    3. Do you plan to implement this specification in your code?
#       If not, why not?
#    4. Do you have any security concerns related to this specification?
#    5. Is the specification accurate and clearly written?
#
#    Your feedback is appreciated!
