Dear all,
Yves, you stated in Pittsbourgh, that you want to go for a BOF. You
already asked for it?
If no we should start discussing, what the purpose/goal of the WG is.
With SLS document, which is I think very premature, it is not clear for
me what the target standard should be in the area of SLS and its
