hmm can we first collect some TE related atrributes that apply both to
OSPF and IS_IS before making that call ?

that one might get hairy pretty soon ... as some vendors define
their leak policy as prefix, lists and some others call into
execution of a policy language.

|    [Eric] Multi-topology for non-standard ones. This model should allow this.

do you have a use-case for this ? - any document that you can refer to ?
