According to BCP 190 [1], the coaps-est draft should not mandate particular forms of URI substructure. So a server should be free to structure URIs as it sees fit, e.g.:

</a>;rt="ace.est"
</b>;rt="ace.est"
</c>;rt="ace.est"
</d>;rt="ace.est"
</e>;rt="ace.est"
</f>;rt="ace.est"

If a client has trouble selecting the right link from the above list (and they all look interchangeable to me), then you'd need to provide more specific link information, e.g.:

</a>;rt="ace.est.skg"
</b>;rt="ace.est.crts"
</c>; rt="ace.est"
</d>;rt="ace.est.att"
</e>;rt="ace.est.sren"
</f>;rt="ace.est.sen"
