    Jim,

    You are correct in your statement that the policy group hosts a lot of
    knowledgeable people on data modeling today, however, i do not agree
    that any effort in protocol independent modeling of information should
    automatically be dropped in the policy framework group.
    That decision is not up to us however, and i would appreciate any other
    views on this issue.

    I personally think multiple protocols can be used to carry the
    information contained in an SLS. In fact, some while ago, some of us
    submitted a draft to the IETF describing the use of PPP/IPCP to
    negotiate a subset of SLS parameters that would apply to the link over
    which the SLS was negotiated.
    This effort was almost immediately blocked by some of the PPP gurus,
    that directed SLS negotiation to 'another' protocol.
    As far as LDAP is concerned, it might not be adequate to offer the
    richness of negotiation required for reaching an agreement between
    customer and provider. However, i would certainly not exclude it.

    cheers
    Yves
